Cher cries with pride during Chaz Bono's routine

Cher was moved to tears as she watched her son Chaz Bono perform on reality TV show Dancing With The Stars on Monday (10Oct11).

The transgender star has been competing with professional dancer Lacey Schwimmer in the TV contest, and on Monday, they performed a high-octane routine to the theme music from boxing movie Rocky.

The performance was especially important to Chaz Bono as he had his family in the audience, including his superstar mother, grandmother Georgia Holt and stepmother Mary Bono Mack, who was married to his late father Sonny Bono.

After judge Carrie Ann Inaba revealed she was moved to tears during the performance, the Believe singer also grew teary-eyed, before giving her son a standing ovation.

The proud mum took to Twitter.com after the show, writing, "OMG! (Oh my God!) I was crying! Wasn't expecting 2 b (to be) so nervous! Broke my bracelet clapping! I'm so proud!! Chaz was great!"
