"They didn't care who saw them and they were acting very flirty the entire night."

While fans are convinced the smooch was just a bit of fun to extend the girls' 15 minutes of fame, Matha's onscreen husband Michael Brunelli was reportedly left furious after seeing the photos.

According to the pubication, the 27-year-old primary school teacher was shocked to learn of the hook-up.

A source told Woman's Day: "Michael thinks Ines is a bad influence on Martha. He'd prefer it if they didn't hang out as much as they do. Their friendship is definitely causing a rift between them."
