Jacob Elordi Hangs With Olivia Jade's Parents On Yacht

Jacob Elordi looks super relaxed around Olivia Jade's famous folks ... doing push ups and hanging with the whole fam on a yacht.

The actor and his girlfriend are on a yacht vacation with her parents, Lori Loughlin and Mossimo Giannulli, and Jacob's keeping things loose around them.

At one point, Jacob got down and started doing push ups in front of everyone ... and they all seemed pretty impressed.

You may recall, we caught up with Jacob and Olivia on another outing on this yacht trip ... and the two were suntanning and enjoying each other's company.

Olivia's sister and her boyfriend are also joining Jacob, Lori and Mossimo on the Mediterranean Sea ... so everyone's getting even more acquainted, and the couple is taking their relationship up a notch.

Check out the gallery ... Like we said, Jacob busted out a few pushups on the yacht and then took off his shirt to show off his toned physique.
