She’s such a beautiful girl. Why she’s wasting her time on someone who is not worth it is beyond me. It’s time to let go. You don’t need him to love you girl. You need oxygen, you don’t NEED him, especially when he is not the first or last man. This just goes to show that being rich and attractive is not an antidote for happiness and self-esteem. Apparently Rihanna spent Saturday night at Hollywood nightclub Playhouse, where the singer and other stars were on hand to celebrate the launch of Pink + Dolphin’s flagship store.

During the evening, the singer was stationed at her own VIP table across from ex-boyfriend Chris Brown. Brown sat with Christina Milian and Sean Kingston as Chief Keef performed.

Although Rihanna, who recently told Oprah she “still loves” Brown, was surrounded by friends, her mind seemed to be elsewhere. The 24-year-old slowly sipped drinks, while “pretending to dance and mingle,” but kept her eyes on “all the fun Chris and Christina were having,” a source tells PEOPLE Magazine.

Rob Kardashian later took a seat at Rihanna’s table where he got a little flirty with her and shared a few laughs, says a source. But, “you could tell she really just wanted Chris to pay attention and talk to her, but he was totally ignoring her.”  If this is true, then I need for Rihanna to get a grip, but I don’t think it’s true… Time will tell.
