The traditionally private couple had some fun at the London premiere of Skarsgard's new film.
Apparently the transition from sexy vampire to King of the Jungle wasn’t an easy one! On Tuesday night, Alexa Chung attended the London premiere of her boyfriend Alexander Skarsgard’s new action flick, The Legend of Tarzan.
Though the notoriously private couple did not pose together on the red carpet, Chung did have a little selfie fun by posting a picture of herself with a poster of her shirtless, ripped beau to Instagram.

“Human. Nature. #tarzan I spent 6 months eating high protein meals 5 times a day and suffering through hefty regular workouts to prepare for this Instagram. Unclear what the other guy did,” Chung quipped.
The couple was also recently spotted out together at the British Summer Time Festival in London’s Hyde Park on July 2.
The True Blood alum has been candid about his difficult regimen while shooting the film.
He recently told Mr. Porter that he consumed “an insane” 7,000 calories per day while also lifting heavy weights. He avoided all sugar, gluten, wheat, dairy, and alcohol.

Recently, Skarsgard jokingly told ET that the strict diet helped him to record Tarzan’s famous cries.
"My trainer was like, 'You're going to get pasta for lunch,' and then I'd open the box and it'd be broccoli, and then they recorded the 'No!'" he said with a laugh.
