Millie Bobby Brown Rocks Skimpy Bathing Suit on European Honeymoon

Millie Bobby Brown‘s enjoying a European getaway with her new husband … and, apparently, their honeymoon’s a family affair ’cause his legendary dad’s right by their side.

The actress hit the beautiful Italian island of Sardinia with her hubby Jake Bongiovi … and, ya gotta see the pics ’cause she’s got a marital glow about her while tanning at their villa.

There’s Millie in the bright orange long-sleeve button-down over her one-piece bathing suit — which didn’t cover up much more than a bikini, we should note.

Of course, Jake’s hanging out with her in his prep school best — white sweater vest and matching shorts … but widen out the frame and there’s papa Jon Bon Jovi crashing what otherwise looks like a honeymoon. It can’t qualify as such when your dad/father-in-law’s there!

Jon’s shirtless in the snap … but, he’s got a big smile on his face — and, Jake and Millie don’t seem to care too much that he’s hanging with them.

As we told you … Millie and Jake tied the knot in a secret ceremony last month after several years of dating — confirmed when they flaunted their wedding rings on a day out in the Hamptons, and then again a couple weeks later when they hit Universal Studios and MBB wore shorts with “Wifey” written on the butt.

The couple was reportedly planning to have a larger wedding ceremony with family and friends … so, that could be why they’re all over in Italy together..
