The popstar, 41, and the former rugby union player, 34, initially sparked rumours they could become romantically involved after their flirty exchanges on X Factor: Celebrity.
They were then spotted on a date together while the series was still airing.
And last night the couple went red carpet official at the Golden Globes in Beverly Hills, California.
The Pussycat Dolls singer wore a pink asymmetric gown while Evans sported a tuxedo as they posed for photographs at the InStyle And Warner Bros after party.
They also both posted a photograph from the main red carpet together on Instagram - and their celebrity friends could not get enough.
Fellow Pussycat Doll Ashley Roberts wrote under Scherzinger’s picture: “Ok hot couple alert” while new Love Island host Laura Whitmore posted two flame emojis. Alexandra Burke also commented with several love heart-eye emojis.
Over on Evans’ page, radio presenter Jenni Falconer posted several flame emojis underneath his photograph.
During her time on Celebrity X Factor, Scherzinger was teased by fellow judges Louis Walsh and Simon Cowell for being “invested” in Evans’ act, called Try Star.
The group consisted of rugby players Evans, Ben Foden and Levi Davis and despite being endorsed by Scherzinger, they were booted out of competition in the final stages, finishing in fifth place.
