Mary Lynn handled it in Avery classy. If Rush had kissed another Hollywood actress, like Angelina, Jennifer Aniston, Susan Sarandon or Janeane Garofalo, they'd have issued a press conference the next day. Mary Lynn never went out of her way to announce she wasn't dating him. The kiss occured five months ago.
She actually refered to him as her boyfriend when she was performing standup. And when she was on the Spike Feresten Show she said "can you blame him?" for kissing her and "I felt violated but I liked it" (the kiss).
BTW, did anyone notice the part of the article where she called Rush, "brilliant and hilarious"? Mary Lynn: I admire your guts for saying that, because most in Hollywood would be to scared to compliment El Rushbo like that. Good for her.
