She's six months pregnant with her first child, but The Saturdays singer Una Healy isn't ready to change into billowing maternitywear any time soon.

The Irish pop star, 30, still looked as sexy as her bandmates as she performed in a gold mini dress at the Capital FM Jingle Bell Ball in London tonight.

Joining Rochelle Wiseman, Mollie King, Frankie Sandford and Vanessa White on the red carpet, she proudly showed off her growing bump in her shimmering number.

All fired up: Una joined her bandmates (L-R) Mollie King, Rochelle Wiseman, Frankie Sandford and Vanessa White on stage

She complemented her bandmates, who were all dressed in gold and white creations to get into the Christmas spirit.

Blonde King, 24, showed off her tanned legs in a bottom-skimming white mini-skirt and gold sequinned top, while Sandford, 22, flaunted her toned figure in a white cut-out dress.

The fivesome performed hits from past and present albums, including Higher, Notorious, Ego, My Heart Takes Over, Forever Is Over and All Fired Up.

Charlie's Angels: The group put on quite a few poses as they worked the stage

Ahead of the Jingle Bell Ball, the group travelled 230 miles after performing at the Echo Arena in Liverpool last night as part of their All Fired Up tour.

Despite being pregnant, Healy hasn't let her expectant state slow her down during rehearsals over the past few weeks.

Mollie said last week: 'Una is such a trouper, she hasn’t missed one rehearsal. We can’t hold her down. There’s no sit-down or wheelchair for her. We’re all up there busting a move.'

Back in the fold: Sandford is enjoying being back in the group after taking time off for health reasons

Glam: The group looked suitably festive in their white and gold outfits

And Una admitted she's been loving the attention on her bump and doesn't even mind when people touch it.

She said: 'It's quite a loving thing. You feel it's because they know it's quite a special thing going on in there. I know some people get freaked out by it, but I like it.'

While The Saturdays looked festive in their gold and white, their contemporary Jessie J wasn't quite into the Christmas spirit yet when it came to her wardrobe.

That's not very festive: Jessie J wore shorts and a floor-length cardigan to the ball

The singer, 23, wore a pair of black shorts, T-shirt and floor-length black cardigan as she arrived on the red carpet.

The annual Capital FM Jingle Bell Ball was hosted by Lisa Snowdon, who presents the station's breakfast show.

She recently lost her partner-in-crime Johnny Vaughan, who is being replaced by Dave Berry.

Also performing at the gig were X Factor boy bands JLS and One Direction.

Their sets came as they hit the No.1 spot in the UK singles chart with this year's X Factor finalists with Wishing On A Star.

The current queen of pop made a return to the Jingle Bell Ball in London and was back to her old tricks.

Rihanna unveiled a new blonde hairstyle which looked like it may have been a wig as she closed day one of the festive concert yesterday.

The We Found Love singer performed a set full of hits at the O2 Arena and strutted around the stage scantily dressed.

Riri wore a pair of extra tiny black shorts with fishnet tights and a houndstooth wrap hanging from her waist.

She managed to stay on her feet despite rocking an extremely high pair of black ankle boots.

The 23-year-old flashed her midriff as she gyrated across the stage and entertained the audience.

Flanked by some denim clad dancers the Bajan performed tracks from her latest album Talk That Talk as well as others including What's My Name? and Umbrella.

The host for the event was radio presenter Lisa Snowdon.

The model wore an orange dress that also had a cape attached to it.

She held the whole day together and introduced all of the acts before they took to the stage.

The opening day began with The Xtra Factor host Olly Murs performing Dance With Me Tonight.

Wearing a checked shirt and a trilby he also sang Heart Skips A Beat and was then joined on the track by special surprise guests Rizzle Kicks.

Olly, who had to rush off to present Xtra Factor, had tweeted about his busy schedule earlier in the day and said: 'Arrived back in London!! HUGE Day ahead!! Am doing @CapitalOfficial Jingle Bell Ball tonight!! Opening show then back for XTRA Factor!! (sic).'

American singer Jason Derulo was next up and he performed a selection of his best selling singles in a glittery silver jacket.

The blonde 20-year-old wore a short black dress with ankle boots.

She told the crowd that it felt 'great' to be back at Jingle Bell Ball.

The multi-talented Labrinth gave perhaps the most rousing set of the evening.

Labrinth surprised the crowd when he sang his own version of Chris Brown's Beautiful People and got a great reaction from them.

He also performed his debut single Let The Sunshine as well as Pass Out and an acoustic version of Frisky.

When he ended his set with Earthquake the arena erupted and the audience went crazy for his number two hit.

DJ and producer Calvin Harris performed a turntable based set ahead of boy band The Wanted.

The Warzone singers made an unconventional entrance on to the stage by walking through the mostly female crowd.
