Mark Salling Celebrates His Birthday With Cory Monteith (PHOTOS)

Happy birthday Mark Salling! The Glee hunk celebrated the big 29 in Vegas at The Cosmopolitan Hotel. With his costar and BFF Cory Monteith, the duo had a great time hanging by the pool at Marquee day club before heading out for the night.

With a select group of pals, the Glee costars danced to the tunes of DJs Markus Schulz and Funkagenda before Mark was surprised with a cake in the shape of an owl.

Mark is actively involved with the Hunter Wildlife Rescue charity. So great!

Salling and Cory had dinner at TAO before the party continued at Marquee later Saturday night with some champagne toasts and friends all around. Mark looked dapper in a checkered blue Central Otago button up by UNTUCKit.

Meanwhile, Adele was playing at the Cosmopolitan as well, which had many celebrity onlookers — both boys said they were big fans! It was Adele’s first-ever Vegas performance which took place at The Chelsea to a sold-out crowd of more than 4,000 fans
