Is kissing during a bachelorette party cheating?

“My fiancé and I are getting married in September. She had her bachelorette party last weekend and I found out that she made out with a few guys at the bar. She’s never cheated, but this has me concerned.
Is this a bad sign for things to come, or is that normal for a bachelorette party?”
