The 27-year-old star was shooting the shirtless scene for the new season of the hit CW show, in which he plays Liam Court, the resident rebel without a cause.
In the scene Matt shows off his toned bod as he hits the beach with his co-star Tristan Wilds who himself has a body to turn heads for.
While on the set, Matt tweeted a photo and wrote: “Just wanted to let you in my world for a sec… My POV on set right now.”
Matt first shot to fame in Bravo’s reality show Manhunt: The search for America’s most gorgeous male model, so he should be used to all the attention.
90210 is currently filming season three around Los Angeles which premiere earlier this month. The new season will run until May 2011 on the CW network.
