The Saturdays' New Mum Una Healy Celebrates First Mother's Day

The Saturday's Una Healy says she can't believe she's celebrating Mother's Day as a new mum for the very first time.

The 'All Fired Up' singer posted a Mother's Day message to her own mum, after giving birth to her first child with fiancé Ben Foden earlier this week (13^th March).

"Happy Mother's Day to my wonderful Mammy Ann and all the fellow Mothers out there," Una tweeted this morning (18^th March). "Can't believe I am celebrating my first already!! :-) xx."

Una and England rugby star Ben welcomed daughter Aoife Belle at the start of this week, and returned home with their new arrival on Friday evening (16^th March).

"Happy mothers day to all the mummys out there, and to my favourite one of ALL not that I'm biased @mumsterking! Love you," Una's band mate Mollie King also posted in tribute to her own mother.

'Notorious' singer Rochelle Wiseman added: "Happy Mothers day to my Mum and all the Mummy's out there."

The Saturdays performed earlier this week for the first time without Una while she spent time with baby Aoife, and the five-piece girl band are already working on the follow-up to 2011's 'On Your Radar'.
