PHOTOS: Ross Lynch Celebrates His 21st Birthday With R5 in Las Vegas!

Look at how hot R5 is for Ross Lynch‘s 21st birthday?!

The band — Ross, Riker, Rocky and Rydel Lynch, and Ellington Ratliff — snapped some new pics before hitting dinner at TAO and the club to celebrate Ross‘ birthday at the Venetian in Las Vegas on Thursday (December 29).

The pics could even double for R5‘s next album, don’t you think?!

Ross‘ girlfriend Courtney Eaton and younger bro, Ryland, also joined the group in the celebrations.
