At 29-years-old she is the oldest member of The Saturdays and she should know better.
But Una Healey seemed to be the ringleader last night and was looking extremely worse for wear as she emerged from Frankie Sandford’s birthday party at Chinawhite nightclub last night.
Dressed in a short black strapless dress with an embellished neckline, the Irish singer couldn’t keep her footing as she left the London hot spot.

The effects of the night were clearly visible as Una lost her battle with gravity and fell back right on to her bottom on the floor.
Una managed to push herself back up off the entrance rug and attempted to keep her balance in her sky-high black heels.
Luckily her trusty boyfriend, Ben Foden was on hand to help his lady as she staggered out of the club and managed to negotiate her entry into the taxi, where band mate Vanessa was waiting.

The 21-year-old accepted Una into her open arms and pulled her into the taxi steadying the singer.
And it seemed that Una was eager to thank Vanessa in her own special way, with a big kiss.
Miss Healy, whose fake eyelashes appeared to be slipping from her eyelid, grabbed Vanessa’s head and pulled it towards her own face and Vanessa giggled at her bandmate’s sudden show of affection.
Whoops! Una failed to keep on her feet and fell to the floor in the foyer of the nightclub

The singer emerged looking relatively fresh-faced this morning as her and the other band mates headed to rehearsals.
And it wasn’t just Una who appeared to have a good night last night and the birthday girl appeared to be in high spirits too.
Frankie, who turned 22 yesterday was looking stunning in a printed nude and purple shift dress teamed with a pair of nude open-toe patent heels.

The girls have been busy rehearsing for their upcoming tour which kicks off in Liverpool on February 15.

But there was one Saturday who couldn’t join in on the raucous celebrations because of an injury sustained during tour rehearsals earlier in the day.
