Pregnant Una shines at the Jingle Bell Ball

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 last night.

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.

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.

Ahead of the Jingle Bell Ball, the Sats 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.’
