Sing it again and again!

Just when you thought anyone and everyone was partying it up at San Diego's Comic-Con, Rob Lowe decided to have a celebration of his own in the comfort of his own home.

Using the popular Dubsmash app, the Parks and Recreation alum decided to bust out into song on his Saturday evening.

And out of all the songs one could choose from, Lowe decided to show a little love for Julie Andrews. Prepare yourselves for a rendition of "The Hills Are Alive" from The Sound of Music.

"This is what I'm doing on my Saturday night," he wrote on social media. "Enjoy."

How could we not enjoy this simple but oh-so-sweet tweet. It certainly doesn't hurt that the 51-year-old is totally shirtless for the impromptu performance. Looking good, dude!

Andrews isn't the only A-list star that Lowe is listening to these days. During a recent trip to the beach, Lowe gave a shout-out to a famous rapper for getting him through the waves.

"Headed to the islands surf on the boat, doing 27 knots," he tweeted Saturday morning. "Listening to @Drake #Enemies Best day yet!!" Talk about a wide range of musical tastes.

One singer who may not be on his playlist is the one and only Ariana Grande. After the "Problem" singer made headlines for her controversial doughnut run, Lowe didn't exactly remain quiet.

"As my grandpa would say: ‘Yeah, sure. Pull the other leg, it plays jingle bells!' #Lame," he tweeted after Grande apologized. "Cannot wait for the new Ariana Grande (sic)/Dixie Chicks jam to drop! #IActuallyLoveAmerica."
