What to do with my overly flirtatious friend?

Okay so one of my closest friends ever!!! Is superrr flirty... and we're going to camp next week. Meaning: TTOONNSSS of guys.. And since she is one of my bffs, ima have to deal with it. But i don't know how. Cause if i do tell her, she's guna say something back at me, and i dont want no drama at all. Ive already tried talking to her.. She also is in a serious relationship, but he takes it seriously while she only does half way. Yeah, she's pretty. But it gets annoying when all she talks about is guys she flirts with. What can i do? Im going to be miserable on what is supposed to be one of the greatest weeks ever!!! But i wanna keep our friendship of course.. PLEASEE help!! Thank youuu!!!
