Star Tracker: Demi Lovato, Zoe Saldana, and Bruno Mars

Demi Lovato looks absolutely gorgeous in her new cover art! Our 19-year-old December/January cover girl dons an au natural look for her new single, “Give Your Heart a Break.” According to Cambio, the part-Mexican singer/actress posted the exciting news on her Facebook page. “If you haven't already heard - my new single from Unbroken will be Give Your Heart a Break,” she wrote. “Definitely one of my favorites from the album :) - xo Demi”

— Part-Boricua crooner looks suave in new promo shots for his upcoming sophomore album, Tr3s reports. The 26-year-old is donned in a retro fashion style and, according to the website, dropped some hints about his album to Ryan Seacrest. “I want to have fun on this next album,” he said. “I think that's the most important key, especially now that I’ve been on the road and am playing a lot of shows. I have a little more of a vision than I think I did with Doo-Wops & Hooligans.” We’re confident this next album is going to be amazing.

Boricua super-star Jennifer Lopez was spotted with her rumored sweetie Casper Smart recently, according to Just Jared. The 42-year-old singer/actress and Smart reportedly tried to remain discreet after making separate exits from a jewelry store in Calabas, California.

Zoe Saldana and her ex-fiancé are resuming business as usual. According to Just Jared, the part-Puerto Rican, part-Dominican Avatar star was spotted with Keith Britton recently in Brentwood, California. Both left an office building together and hugged goodbye before Saldana headed to her car. No further details were given about the nature of their meeting, but we think it most likely has something to do with, the new fashion website that both Saldana and Britton co-founded.

— The always-cheery David Archuleta was in Santa Ana, California recently to sign autographs. According to Just Jared Jr., the 20-year-old singer/songwriter was at Deseret Books this past Saturday. Archuleta is currently wrapping up his “My Kind of Christmas” tour and recently said in an interview that he finds something special about Christmas music. “You’re able to put your heart into it a different way than with other, just pop, stuff,” he said.
