As a superstar singer and X Factor judge Britney Spears is a regular on the red carpet.

Not so for her fiance Jason Trawick, who is more usually seen in sweat pants fetching her coffee.

But he pulled his suit out of storage last night to make a rare appearance at her side on the red carpet.

And the 40-year-old certainly scrubbed up well, looking at ease as he played the dashing escort to a glowing Britney.

Britney herself looked her best in her glamorous backless white dress.

The 30-year-old wore her hair in ringlets over her shoulder in order to show off her glimmering gown.

In a recent interview Trawick revealed that it was Britney who made the first move.

'It
was kind of one of those things where she moved, like, turned around,
so we were face-to-face and then …' he told the October issue
of Elle magazine.

The pair got engaged last December and sources say they plan to wed after Britney completes her commitments with X Factor USA.
