No jacuzzi for Robert Downey Jr.

Robert Downey Jr. and his wife were invited to join Chris Evans in as steamy hot tub session with Chris' new "hot girl".

Downey told Variety: "I have a vague memory of seeing him and whatever hot girl he was dating across from a dinner with me and Susan. I think he and his girlfriend invited Susan and I back to their house to get in the Jacuzzi, to tell you the truth".

He didn't know about intentions or details of the evening event, but he insists he politely declined the invitation.

He joked: "[Did we join them?] No, we did not, and by the way, like I said, that's a vague memory, but that's what I'd like for you to print".

Downey is such a big fan of Chris' lead role in the 'Captain America' franchise, that for his birthday celebration he intends to host a special screening for the upcoming sequel 'Captain America: The Winter Soldier'.

He said: "I'm not kidding. I'm having 50 kids over and I'm screening 'Captain America 2' on my birthday, which happens to be the day it opens. I haven't seen it. That's one of the perks of being on the inside track at Marvel. I hope it's not watermarked too heavily".
