Bono is currently preparing for tonight's Broadway week dance with partner Lacey Schwimmer. The pair scored 21 out of a possible 30 points for their 1980s-themed performance on last week's show.
Supporting Bono on her official Twitter account, Cher said: "To all that think I shouldn't support Chaz on DWTS .....it's true he is my beloved child! Is he the Best Dancer prob. Not! Is he working his ass off & Having the time of his Life? YES!
"Do people Seem to see his kindness & His Fathers sweet looney side? Yes? Do what u want to do! I'm not the Fkn master of the Universe I JUST WANTED MY CHILD TO HAVE FUN! HE IS! Let people think what they will about me! (sic)"
Bono and Schwimmer will be dancing the tango on tonight's show, and revealed via their Twitter accounts that they will be the fifth couple to take to the dance floor.
Cher attended a taping of Dancing with the Stars earlier this season where she became tearful while watching Bono and Schwimmer perform, later posting on Twitter: "OMG, I was crying! I wasn't expecting 2 b so nervous! Broke my bracelet clapping! I'm so proud!"
Bono was joined by some of his Dancing with the Stars colleagues at the Gay, Lesbian and Straight Education Network (GLSEN) Respect Awards over the weekend, where he was handed the Hero prize.
Dancing with the Stars continues tonight on ABC
