Mum-to-be Una parties in style after O2 triumph

PREGNANT singer Una Healy celebrated in Dublin to mark the end of The Saturdays' successful tour.

The star, who announced her engagement to rugby hunk Ben Foden last week, looked stunning as she dressed in a thigh-skimming, sequinned black dress to party with her pals after their gig at the O2 last night.

Tipperary native Una (30) sipped at non-alcoholic drinks while the group wound down after wowing fans at their final performance of 2011 with their sexy ensembles and sultry singing.

Despite nearing the end of her pregnancy, Una showed no signs of tiredness, and danced until 2.45am before heading back to her hotel.
