Jen's former beau sounds off on her big Oscar win...what did he have to say about his ex?
"I'm very, very happy for her," he told E! News about Jen's big win, adding: "I'm thrilled!"
Aww! The two first met while they were both filming X-Men: First Class back in 2010, where they played love interests.
In the December 2012 issue of Elle, Jen gushed about her guy, saying: "He is honestly my best friend, and hopefully I'm his best friend, too. He's my favorite person to be around and makes me laugh harder than anybody."
The couple reportedly split in January, but it's clear they've remained on great terms.
