Year In Review 2012: Top Celebrity Relationship Stories of 2012 [PHOTOS]

Number One Celebrity Relationship of 2012:

It has been quite a roller coaster ride for Rihanna and Chris Brown, making them the top celebrity couple of 2012. From questioning whether they are still actually together or not, to the love triangle with Karrueche Tran, it remains unclear what the true relationship status is between this young famous duo. But that doesn't make them any less memorable.

In August, the Barbadian singer opened up about Brown for the first time in an exclusive interview with talk-show host Oprah, admitting that he was her first love, and that she still believes he is the love of her life.

In September, at the MTV V.M.A. Awards, Rihanna won the Video Of The Year prize. As she exited the stage, Chris Brown congratulated her. They were seen briefly kissing on the lips, and embracing, though Brown had a longtime girlfriend, Karrueche Tran, at the time.

Fast forward to the present day, and it seems clear that something is going on between the pair. Brown in October broke up with Tran, over his friendship with Rihanna, and they have been spotted at various nightclubs and hotels together.

They have even posted pictures of each another on their social media accounts. It remains to be seen where this relationship will head, but it is evident that Rihanna and Chris Brown can't stay apart for too long, despite their on-and-off again status and Brown’s domestic abuse past, which caused them to originally break up in 2009.

Second Top Couple Of the Year: The second top couple of the year is none other than hip-hop power couple Jay-Z and Beyonce.

They had an amazing year, and Beyonce gave birth to their first child, daughter Blue Ivy, on Jan.7. The couple had been together for 10 years.

Blue Ivy clearly is already living the good life. Earlier this year, Jay-Z told talk show host Oprah, "At the end of the day, I just know I'll probably have the worst, most spoiled little kid ever." The rapper spent $600,000 on a solid-gold, handmade horse from Japanese jeweler Ginza Tanaka for Blue Ivy; and Beyonce and Jay-Z reportedly spent $1.5 million on other gifts for Blue Ivy.

This year, Jay-Z and Beyonce actively campaigned for President Barack Obama’s re-election, and Jay-Z appeared in an advertisement endorsing Obama and performed at his final rally in Ohio before election night.

Beyonce posted a picture to her Tumblr account that read, “TAKE THAT MITCHES,” written on notebook paper the night Obama was re-elected.

She is set in February to perform at the 2013 Super Bowl and to come out with new music, according to music producer the Dream. It is clear that next year we will see a lot more of the superstar duo.

Third celebrity couple of 2012: The third couple to make the list is model Amber Rose and rapper Wiz Khalifa. After dating for a year, they were married in March, and the affection they have showed in public has won over their fans.

The model had dated rapper Kanye West, and then accused West's current girlfriend, Kim Kardashian, of being a "homewrecker" and sending West an array of photos and texts while he was still with Rose.

After the relationship with West ended, Rose said she was able to find true love with Khalifa. "I want to thank her," Rose said about Kardashian. "Because if she was never a homewrecker, then I never would have met Wiz, and I wouldn't be as happy as I am now."

At the MTV VMA Awards, Khalifa announced that Rose was pregnant. Khalifa told MTV's Sway Calloway on the red carpet: "We're expecting a beautiful lil baby -- me and Amber. We're so excited. We're having a baby!"

Earlier this month, Khalifa also told Hot 107.9 that he is thrilled to become a father and discussed the couple's wedding plans on the radio show.

"[We will have it done] before or after I get off tour. You just sign the paper or whatever and it’s like a legal thing, like ‘Bam!’, you’re married,” Khalifa said.

Rose is expected to give birth to their "rosebud" early next year.

Celebrity Couple Number Four: Kanye West and Kim Kardashian also made headlines throughout 2012. They began dating in April, and seem to still be going strong. Eight months for Kardashian, whose marriage to NBA player Kris Humphries lasted only 72 days before she filed for divorce, is impressive for the starlet.

West has rapped about her, such as in his song, "Way Too Cold," formerly titled "Theraflu." In the lyrics, he describes being in love with Karsashian while she was dating Humphries. Most recently, he dedicated a song on his album, "Perfect B****", to her.

Though the term of endearment may be questionable, the song, according to a New York Daily News source, is about his search for the perfect woman, and how he has now found the "perfect b****" in Kardashian.

Not to be outdone, Kim Kardashian made sure to stand by her man, as well. After West collaborated with designer Giuseppe Zanotti to create pearly knitted stilettos, Kardashian recently took to Twitter to post a photo of herself wearing West's footwear. She has also tweeted a picture of herself wearing gladiator knee-high boots from his women's line, DW Kanye West.

While Kardashian has been publicly displaying her love for her new boyfriend, she insists that it is for real.

In an August interview with Oprah Winfrey, Kardashian said, "I couldn't sacrifice my heart for a publicity stunt."

Number Five Couple Of 2012: Justin Bieber and Selena Gomez made the cut as celebrity couple number five of 2012. They were a Hollywood “it” couple for two years before calling it quits in November. Before the pop star's Boston performance on his "Believe" tour, Bieber went to a radio interview where he was asked about the breakup.

"I don't know what to say. I don't know what's going on in my life. To even assess that, it doesn't make sense, ’cause I have not made any comment,” Bieber said.

Hours later, during his concert, Bieber sang a song that is not on any of his albums — Justin Timberlake’s “Cry Me a River.” The slow-song has been speculated for years to be about Timberlake’s relationship with ex-girlfriend, Britney Spears, and her cheating ways.

Earlier that week, there were rumors, not about Gomez cheating, but about Bieber playing the field with a Victoria’s Secret model, Barbara Palvin. He performed at the 2012 Annual Victoria’s Secret Fashion Show, surrounded by the world's top lingerie models, and Gomez was nowhere in sight.

Although the couple have split up, they have been seen together, so it is possible the young pair may work things out for 2013.
