CHAZ BONO has decided to wed – and sources say his superstar mom CHER has volunteered to pick up the tab!

The former Chastity, Chaz recently announced plans to wed longtime girlfriend Jennifer Elia in Palm Springs, Calif.

“I actually think that’s where we’ll do it,” Chaz, 42, told a reporter. “I love Palm Springs. It’s a place of relaxation and peace and tranquility. Even Rocco our dog loves coming out there.”

Chaz – whose fatherwas the late Sonny Bono – wants his stepmother, U.S. Rep. Mary Bono Mack, to officiate the wedding, which she is authorized to do under California law.

As The ENQUIRER reported previously, Chaz’s bombshell memoir “Transition: The Story of How I Became a Man” sent mom Cher into an emotional tailspin after he claimed that she belittled him and refused to accept his gender-bending lifestyle.

But the Oscar-winning star has recently come to terms with her former daughter’s sexual identity, said a source.

“It took a lot of work and soul searching, but Cher loves Chaz and says she’ll stand by his side when he marries Jenni­fer,” a family insider revealed.

“Cher has already told Chaz that she’d be honored to throw Chaz the best wedding Palm Springs has ever seen.”
