“Nobody Like Us” may be the most highly anticpated song off Justin Bieber’s new album, "Believe Acoustic," which he revealed is about his ex-girlfriend, Selena Gomez.

“My acoustic album will let u know how I feel about what is going on in my life instead of rumors guessing,” the 18-year-old artist tweeted recently, according to MTV.

“Nobody Like Us” has lyrics such as “Tell me, was it worth it/we were so perfect/but baby I just want you to see/ there's nothing like us/there's nothing like you and me/together through the storms/there's nothing like us.”

Earlier this month, Bieber told Billboard that this "Believe Acoustic" will be about telling people the truth about his love life and admits that he does not read about the rumors but hears about them through friends.

“There's so many rumors. People say I call Selena every day and she won't pick up the phone or I'm chasing her down, and these are all fake stories. I don't go on blogs or anything like that.

I hear things. People tell me if something happens on the Internet. It gets back to me, definitely.”

The lyrics to “Nobody Like Us” go on to say, “I gave you everything baby/everything I had to give/girl why would you push me away?/you know I'm used to making your day/but that is the past now/we didn't last now/I guess that this is meant to be.”

Meanwhile, Gomez made headlines earlier this month when she sang at a private concert benefiting Unicef and made several cryptic references to moving on from her former flame.

"I've been through a lot the past few months. It's been weird and sad and cool," she told the crowd, according to Us Weekly, before singing a cover of Justin Timberlake's scorned lover's anthem, "Cry Me a River."

"This song definitely speaks to me," she admitted.
