What's the rush!? Lauren Graham has been dating her Parenthood costar Peter Krause for nearly five years, but the actress admits the pair have no immediate plans to tie the knot. The Gilmore Girls alum let Ellen DeGeneres down gently during an appearance on her show on Thursday, March 20.

"You've been together for several years," DeGeneres, 56, said.

Graham, 47, turning red, replied, "Yeah, over four." Then DeGeneres flat out asked whether the two would ever get married.

"Phew, suddenly it's like I'm talking to my grandma. It's all she wants to know," Graham joked. "I don't know. We are very happy as we are and I never have a good question for this answer."

"Well, just tell the truth for a change," DeGeneres said, egging her on. "Just answer the question."

"I don't know! We are really happy," Graham gushed of Krause, 48. "I feel like close to five years in Hollywood, its like, aren't we married already really? It's good the way it is."

She added: "I'm tempted to be like, 'Big announcement everybody!' But that would be a lie."

Graham and Krause first began dating after meeting on the set of Parenthood in 2010. The pair play siblings Sarah and Adam Braverman on the NBC series.
