Sultry singer Ciara attended a Samsung event in Hollywood yesterday wearing a sexy sleeve dress that left nothing to the imagination. Prior to attending the event, Ciara was spotted shopping at Barney’s in Beverly Hills earlier in the day. All she needs is one hawt single and she’ll blow away the competition, ie Rihanna and Beyawnsay.

Rap star Nicki Minaj and singer/actress Jennifer Hudson (not pictured) attended the Samsung Infuse 4G For AT&T Launch Event held at Milk Studios in Hollywood yesterday. She’s not happy because this is one of those rare occasions when Nicki is dressed down per the request of her sponsor.

Sexy superstar Kelly Rowland also attended the Samsung event. Kelly Rowland’s hit single “Motivation” sits at #3 on the Billboard chart. But she’s not letting the newfound fame get to her head like Beyawnsay did. Kelly is already a superstar in Europe.
