While many Americans were celebrating Memorial Day with hot dogs and Bud Light, Ian Somerhalder had a work-filled weekend across the pond!

After delighting fans with his appearance at Eco-Con 2013, the Vampire Diaries actor hit the town to promote the Russian translation of The Power of the Actor, a 12-step technique created by his acting coach Ivana Chubbuck.

But Ian’s jam-packed weekend didn’t stop there. The blue-eyed heartthrob also sat on the panel of the Cinemotion Acting School Press Conference and attended "Circo Fantastico Del Senior Toras" at Moscow’s Premier Lounge. In fact, while partying it up inside the world-renowned club, Ian turned heads when he was seen cozying up to a sexy mystery brunette.

Needless to say, it was a crazy weekend that didn’t provide nearly enough sleep. Before heading to bed in the wee morning hours of Monday, May 27, Ian took to Instagram to say goodnight to his many fans.

“1:53 AM,” he wrote, alongside a photo of his shirtless chest. “Moscow-I love you but you have almost killed me. In the best way possible...”

Now, that’s what we call celebrating Memorial Day!
