President Barack Obama is joining the cast of Entourage, sort of.

The HBO show's star Adrian Grenier announced on his official Facebook page on Friday that he would make an Entourage movie if Obama agreed to make a cameo — and he's agreed, Grenier claims.

"I promised to make the Entourage movie if he would do a cameo. He agreed," Grenier said, posted above a photo of himself with the President.

"Seriously."

If it's true, Barack won't be the first Obama to make the leap to the big screen.

His wife and the First Lady, Michelle Obama, has made appearances on Extreme Makeover: Home Edition and Nickelodeon's iCarly.

Entourage had a successful run on HBO from 2004 until its season finale in 2011.

HBO劇集《明星伙伴》（Entourage）于去年全劇終，該劇制作人道格·艾林（Doug Ellin）自劇終后一直在籌備電影版的拍攝，近日該劇主要演員艾德里安·格尼爾（Adrian Grenier）在Facebook爆料稱美國總統(tǒng)奧巴馬已答應(yīng)客串該劇電影版。

艾德里安在Facebook上發(fā)布了配圖的圖片，并發(fā)文稱“我保證過如果他來客串電影版，我就會演，他答應(yīng)了，我沒開玩笑?！?/p>

奧巴馬曾于2008年表示過自己喜歡看HBO的兩部劇集——《明星伙伴》和《火線》（The Wire），去年12月接受《人物》雜志采訪時，他提到最近喜歡上了HBO的《海濱帝國》（Boardwalk Empire）和Showtime的《國土安全》（Homeland），他還喜歡和女兒一起看家庭喜劇《摩登家庭》（Modern Family）。
