Valentine's Day can sometimes be the worst day of the year if you're single, but Tulisa wasn't going to let her solo status get her down as she hit the town with pals last night.

The X Factor judge put her woes with ex-boyfriend Fazer behind her as she celebrated the romantic day with a night on the tiles.

And she wasn't short of admirers either as she showed off a huge card and bunch of balloons in pictures posted to Twitter.

Tuilsa - who split with Fazer last month - was grateful to her mates for showing her a good time on what could have been a depressing day, thanking them for "taking care of their dog".

"Sick night wid @CoreyChorus @tydollasign @rachelrabin ..cc I give u props!Thanks 4 takin care of ya dog on Vday!2 much love xxx," she tweeted.

After spending the day lazing around an LA pool with her PA Gareth Varey, Tulisa glammed up for the evening, sporting a bright red graphic dress, continuing her LA fashion offensive.

Since her arrival in the states, the N-Dubz singer has showed off an array of colourful dresses and playsuits.

But there was one style slip up on Monday as she reverted back to type in a grey velour tracksuit.

It was a far cry from the glamorous looks she has been sporting stateside, and reminiscent of her pre-X Factor days, before the intervention of a stylist and make-up artist.

The star is in the US to record her debut solo album, and it appears Fazer will still be heavily involved despite their split.

He told MTV News earlier this week: "It's going really well, she's got some great records for her album. I've produced Tulisa's first single that's going to be coming out.

"She's shooting the video this week in Miami. I've done three records at the moment for Tulisa and she's currently completing the fourth one."
