Seth Rogen and wife Lauren Miller Rogen threw the 37-year-old actor a star-studded bar mitzvah on Saturday, as part of their annual Hilarity for Charity variety show in Hollywood.
Bar mitzvahs, or coming-of-age ceremonies and parties, are typically thrown for Jewish boys at age 13. Now that he has been bar mitzvah'd, Franco is officially a man, according to Judaism.
"I thought I already was one, but today is the day," Franco told E! News. "It feels good."
And nothing says becoming a man like being treated to a racy performance by Miley Cyrus.
Dressed in a shimmering blue thong leotard, a giant blue Star of David and matching wristbands, as well as silver thigh-high platform boots, the 22-year-old pop star took to the stage to perform for Franco and the rest of the guests. She sang songs such as "Super Freak" and "Shout."
Franco is technically fully Jewish, as his mother's ancestors were Jewish, but was not raised in the religion. Franco had had a bar mitzvah ceremony, with a real rabbi, earlier this month. Parts of it were screened at the gala.
Rogen himself performed at the event, which was presented by Funny Or Die, go90 and SVEDKA vodka and benefitted the Alzheimer's Association. Wearing a tallit, or prayer shawl, Rogen sang a musical number from Fiddler on the Roof. The actor later told the audience the bar mitzvah couldn't continue unless Franco underwent a circumcision, which are typically performed on Jewish baby boys, by a rabbi.
A gurney was wheeled onstage and the actor got on it. Jeff Goldblum appeared onstage, dressed as a rabbi.
Franco was covered up by a curtain just as Rabbi Goldblum was about the perform the ritual, a pre-rcorded video of Zac Efron was then screened. His role? The actor played Franco's "foreskin" and joked he has protected him for a long time.
"Tonight has been f--king eventful, I mean, Zac Efron as your f--kin' penis, foreskin, that's a famous dick you got there, we all knew that anyway!" Cyrus told the audience.
Bill Hader, Kyle Kinnane, Justin Willman, Ron Funches and Al Madrigal also appeared onstage. The band HAIM also performed the Israeli folk song "Hava Nagila" as audience members danced and Franco was lifted up in a chair.
"James never had a bar mitzvah and he mentioned that to me 15 years ago and it's one of those things we've talked about over the years and we needed a theme for this year's event, and we thought, we could give James Franco a bar mitzvah and hold a charity event," Rogen told E! News. "That seemed like a good opportunity—you don't pass on that."
