She may have gotten a new ring from boyfriend Matt Rutler, but there's no engagement to report for newly divorced Christina Aguilera.

The 'Burlesque' star, who turned 30 on Dec. 18, received a ring from Rutler for her birthday, but it's not what you think.

"It's not an engagement ring and they're not engaged," a source told PEOPLE. The ring was apparently a surprise for Aguilera.

While there's no wedding in the works just yet, the singer and her new beau have been spending a lot of time together, and with family members, including Aguilera's mom, brother and sister.
