Christina Aguilera Happily Rang :There's reason for her new positive outlook. Aguilera, who turned 30 last month, has been pictured looking cheerful with rumored new beau Matthew Rutler, her baby boy Max turns 3 this month, and her new movie Burlesque has scooped up several Golden Globe nominations..........

Christina Aguilera's New Beau Is a 'Solid Guy All Around':Christina Aguilera announced she had split from husband Jordan Bratman in October after almost five years of marriage, and now she's moved onto romancing set assistant Matt Butler. Helen Breuer, one of his oldest friends, says the hunk is incredibly thoughtful and attentive.

Helen told RadarOnline.com: “He’s just a solid guy all around.

"My mother was elderly and Matt was always all too happy to help her out, especially when it was snowing. He shoveled our walk way and he helped my mom to and from the house.

"When all the other kids were out sledding, Matt would be helping us out.”

Christina, 29, admitted last week she had strong feelings for Matt, whom she started dating after they met on the set of her latest movie Burlesque.

The singer, who has a two-year-old son Max with Jordan, said: “There's a love there, yes.

"Matthew is a special person. We had a really strong friendship on the movie. He's the kind of person you could spend hours on the phone talking to and all of a sudden it's daylight.”

However, the blonde beauty admits she is taking her romance slowly.

She added: "I just left a five-year marriage. I'm taking it slow and trying to be happy. I'm having fun, I'm dating and it's something I haven't had in a really long time."

Christina Aguilera has rebounded quickly from her recent divorce.

The singer has been spotted out with Matthew Rutler, a production assistant and a guitarist in the Nate Mott Band. The two met on the set of Burlesque in February and quickly bonded - much to the chagrin of friends.

“Christina is completely taken with Matthew," a source tells Star. "But he’s a wild rocker type with a reputation as a ladies’ man."

An insider says Rutler is in "heaven" because he's dating a celebrity.

“He networks like crazy with all the big names she introduces him to. He’s a major operator. And everything is on her dime, because he’s broke. Matt used to live in a crummy apartment with roommates; now he’s at her Beverly Hills mansion every night."

While pals worry that this relationship is "too much, too soon" for Christina, she isn't letting any personal issues affect her work. Check out a series of recent performance by Aguilera in her THG video section.......
