Matt Damon and his family spent this week vacationing in Australia with Chris Hemsworth and his family — talk about a couple hot dads running around the beach, eh?

Unfortunately, a day at the beach turned into a minor debacle when Matt’s daughter Stella was stung by a jellyfish on a beach near Byron Bay.

The youngster apparently screamed and ran to shore, reports the Courier Mail, and the 46-year old father of three wasted no time when he heard her screaming, running to a nearby cafe and grabbed a pack of ice for her wound.

After he iced the sting, his family called paramedics to give Stella some professional help.

Thankfully everything seems to be okay now.

The jellyfish’s reps have declined a request for comment.
