Sisanie debuted her baby bump at the iHeartRadio Jingle Ball presented by Capital One at The Forum in Los Angeles on Friday, December 1. Sis joined Ryan Seacrest and the rest of the clan -- Patty Rodriguez and Tanya Rad -- onstage at the KIIS-FM hosted bash.

Our fave mom-to-be donned a gold jumpsuit and emerald green suede jacket, perfectly accentuating her growing belly. 

“Do you think all 3 of us are smiling in this picture right now? #twinpregnancy #bump #iheartjingleball #kiisjingleball,” Sisanie captioned a cute photo from inside the broadcast room. 

Relive when she broke the news to us live on air that she was having twins here!

The twins made their #iHeartJingleBall debut tonight, along with the rest of the OAWRS crew ❤️❤️
