Singer Adrienne Bailon looked like she may have had work done to her face when she attended Jay-Z’s 40/40 Club’s 10 Year Anniversary Party Monday night. Other stars in attendance for the event included rapper T.I. and his wife, Tiny, New England Patriots owner Robert Kraft, New York Knicks forward Amar’e Stoudemire and singer Maxwell.

Though Bailon looked stunning in a red gown that showed off her assets, most attention was paid to the former “Cheetahs” star and 3LW singer’s face. In addition to extremely long false eyelashes, Bailon was also wearing a bun, which may have caused her face to appear more tightened than usual. She also had a seemingly surprised facial expression in photos. This usually is the case when someone injects Botox and fillers into their face for cosmetic purposes.

The 29-year-old beauty dated reality star Rob Kardashian from 2007 to 2009 and broke up with him after he cheated on her. While dating, Kardashian got a large tattoo on his chest of the singer’s name.

Last month, Bailon spoke candidly about their relationship. "You know, it's like one of your first loves and from so back in the day," she said during a radio interview with Zach Sang.

"Even though things didn't go right, you look back at it five years later, and you're like, 'Damn, that was nice what it was. What we had was great, and it didn't work out.' You move on, and you grow from it. You don't hold any bad feelings towards that person because it was so back then."
