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.. In any case, lots of fun times here .
.. though we hope JBJ's staying far away from .
