Photo Flash: Pop Sensations R5 Open New Year's Shows at The Venetian Las Vegas

Pop powerhouse quintet R5 kicked off their New Year's concerts at The Venetian Las Vegas on Tuesday, Dec. 29. "Dancing with the Stars" fan favorite Mark Ballas opened the show with his newly formed band Alexander Jean, followed by an electrifying DJ set by R5 brother Ryland Lynch, which geared up the fans for a night of energizing hits from the pop rock sensations. Scroll down for photos!

R5 performed in front of an enthusiastic crowd who sang along to their chart-topping hits such as "Smile," "Cali Girls," and "I Want You Bad." The concert was extra joyous because lead vocalist/rhythm guitarist Ross Lynch celebrated his 20th birthday in front of an audience of his most loyal fans.

"Welcome to my birthday party" exclaimed the heartthrob, before taking fans through a spirited set list which also included homages to Las Vegas favorites Frank Sinatra and The Killers.

Ross ended the show with some words of wisdom, "Life goes by so fast and you have to appreciate every single second of it."

R5 will perform on Thursday, Dec. 31 at 7:30 p.m. and Friday, Jan. 1 at 8 p.m. Tickets are now on sale and available by purchase at www.venetian.com or by calling (702) 414-9000 or (866) 641-7469.
