Christmas arrived on Sunday night at The Grove for the annual Tree Lighting Spectacular presented by CITI. And everyone got into the spirit of the holiday season! The uber-festive (there was even real snow!) event was hosted by Mario Lopez and his noteworthy dimples, and included performances by the reunited Backstreet Boys, Colbie Caillet, American Idol Season 11 winner Phillip Phillips, Scotty McCreary, Rickey Minor and His Band, Far East Movement, and a duet by Michael Bolton and Grammy-nominated singer Melanie Fiona, who just came off a tour with Mary J. Blige.
