Lindsay Lohan, Kelly Ripa And More: Celebrities At Z100's Jingle Ball [VIDEO And SLIDESHOW]

While attention was focused on the performers at Z100's Jingle Ball, there were plenty of celebrities on hand to watch Justin Bieber, One Direction, Taylor Swift and The Wanted. A woman who was perhaps the biggest celebrity there, Lindsay Lohan, did not walk the red carpet, but she was there.

Lohan was not officially a part of Z100's Jingle Ball, and her presence went unannounced officially, but she could be seen backstage. Rumors have been swirling that Lohan was there to see The Wanted's Max George, and many speculated that she would make an appearance at Madison Square Garden that night. Lohan was trying to be candid and low-key while attending the Jingle Ball, but iHeartRadio managed to capture a tender moment between Lohan and George.

In the video, Lohan is seen hugging George backstage at the concert. George also spoke about Lohan, saying “She's a good girl,” to the Huffington Post. Lohan was also seen in Philadelphia and Boston, two previous Jingle Ball stops where The Wanted performed.

Lohan was just one of many celebrities at Z100's Jingle Ball. Children were also big part of the night, as many celebrities arrived at Jingle Ball with kids in tow. Kelly Ripa, host of “Live! with Kelly and Michael,” was on hand with her three children. Supermodel Christy Turlington also attended with her children, and Donald Trump Jr. was on hand with his daughter.

Jordyn Wieber also made an appearance at Jingle Ball. Wieber won a gold medal at the 2012 London Olympics in the Gymnastics team competition.

Chloe Grace Moretz, Peter Facinelli and Bridget Mendler were just a few of the other stars who attended the concert. Kelly Kiloren Bensimon, from “The Real Housewives of New York City,” as well as Maksim Chmerkovskiy, Val Chmerkovskiy and Pet Murgatroyd, from “Dancing with the Stars,” were on hand as well.
