Jennifer Anistonturns 50 on Feb. 11, andEllen DeGeneresalready has her birthday plans in the works.

“I’m doing a party for you, on this show,” DeGeneres said. “I am going to have an entire hour — you know how fun my birthday is, you’ve been here for my birthday. And you know how special and surprises and stuff. What if we have your birthday here, for the whole hour, we celebrate you? I meant it.”

Aniston was totally sold (“I love that idea”) — though she did propose another way to mark the occasion. “Is it greedy of me to say that then we go to your house and have an afterparty?” she asked.

“We’ll talk about that, we’ll figure that out,” DeGeneres said. “That’s probably not going to happen.”

DeGeneres said of Aniston’s upcoming milestone, “You look fantastic — you should be thrilled.”

“I feel fantastic,” Aniston replied.

When DeGeneres called her 50th birthday a “big one,” Aniston joked, “It is — stop saying it.”

Aniston’s “fantastic” mood is partly due toher boxing sessions with trainer Leyon Azubuike, who Aniston calls her “gentle giant.”

“He calls me champ, and it’s not weird!” she said, later adding, “I never thought someone would be able to call me champ and I would be okay [with it]. ‘Hey champ! We gotta get [your heart rate] up to 80, champ!’ ”

In an interview for InStyle‘s September issue, Aniston spoke out about the “misconceptions” about her single life.

Aniston continued, “And second, those are reckless assumptions. No one knows what’s going on behind closed doors. No one considers how sensitive that might be for my partner and me. They don’t know what I’ve been through medically or emotionally.”
