So sweet!

While out at the City of Hope Charity Gala in LA on Oct. 11, X Factor judge Britney Spears had quite a good time with her beau Jason Trawick.

The 30-year-old songstress, dressed in a gorgeous Halston number, shared the adorable photo (see above) on her Twitter account — and though it's quite silly, we have to say she looks absolutely stunning!

"She looked beautiful," an eyewitness tells Life & Style. "She was doing her thing and taking some photos."

Britney has been quite busy these days with her role as a judge on the hit Fox show The X Factor. The star, who is coaching the teen group, will narrow down the acts with the help of guest mentor on tonight's episode airing at 8 p.m. ET.
