Kelly Rowland may have been sacked from The X Factor – if reports are to be believed – but it doesn’t seem to be getting her down any.

The stunning star was reportedly told by Simon Cowell that her services would not be required on this year’s series of the hit ITV show, as she failed to connect with the audience and didn’t show enough commitment to the show or her acts in 2011.

But Kelly could not have seemed less bothered when she showed up to the Power of Love Gala, celebrating Muhammad Ali’s 70th birthday at the weekend, when she showed off in no less than three stunning dresses!

She walked down the red carpet and posed for photographers in a stunning pink floor length satin gown. Not content with impressing in the stunning outfit, Kelly later changed into a one shouldered gold embellished dress for her performance and also showed off in a less constraining yellow mini dress.

The event was organized by Keep Memory Alive, and proceeds will be donated to the Cleveland Clinic Lou Ruvo Center for Brain Health and the Muhammad Ali Center, an educational center in Louisville, Kentucky.

The event was incredibly star studded, attended by legendary singer Stevie Wonder, along with stars such as Snoop Dogg, Neyo, Lenny Kravitz, Anthony Hopkins, David Beckham, Samuel L. Jackson and Tony Danza. Stevie, John Legend, Kravitz, Slash, Kelly Rowland and Cee Lo Green all performed.
