These two are definitely feeling the love.

It looks like Maksim Chmerkovskiy's new tour, Maks & Val Live on Tour, is a success so far, as Chmerkovskiy celebrated the tour's opening night with a passionate kiss from fiancee Peta Murgatroyd. Not one for shyness, Murgatroyd posted the PDA to her Instagram on Wednesday, along with a sweet note to the 36-year-old dancer.

"I am so proud of you," Murgatroyd captioned the steamy pic. "Your opening night blew me away baby and all throughout was so overwhelmingly joyous. The stage was on fire, the cast comradery was infectious...I love you and everything that you are."

It's certainly been a great year for Murgatroyd and Chmerkovskiy. She won season 22 of Dancing With the Stars with partner Nyle Dimarco, and his new tour continues through the summer. As if that weren't enough, the recently engaged couple also has a baby on the way -- and the their favorite way to celebrate all year round? With a little PDA!

Of course there's this dirty dancing gem we can't forget:

And a whole lot more where that came from:

The Maks and Peta PDA plane is going to have to cool its jets, however, as Chmerkovskiy will be on the road with the Our Way tour until it wraps in mid-August. Not to fear, Peta -- we know exactly how Maks will be spending his time -- he and brother Val recently gave ET a sneak peak at the show, and dished on what's to come.
