My 53 year old friend

I’m 36 and single. My colleague who is 53 married and has a 19 year old son met a guy friend of mine who is 38 at my house party. He is married as well. Now she constantly tells me this guy has been messaging her and flirting . She tells this about all the men she meets. She thinks everyone wants her. He also tells me that she messages and flirts. They sent me screenshots of their conversations trying to prove who is flirting more🤦🏻‍♀️. They both don’t know that the other person is also sending me screenshots of their chats. I’m disgusted and annoyed by both of them . But more by her . Am I being too judgemental? Could I say anything to her or should I just ignore ? Or should I say something to him. Because she is telling everyone about it .
