Una and Ben Foden have shared the first picture of their newborn son Tadhg.

In one shot, the gorgeous five-week-old looks up at his proud dad as he tickles his little boy's tummy.

Mum-of-two Una, 33, gushed: "My heart could burst with how in love I am x"

The couple welcomed Tadgh – pronounced 'Tigue' - in February. Tadhg is an Irish name and is pronounced 'Tigue'.

Rugby player Ben announced the news on Twitter revealing that his new son already had a full head of hair – as you can see from another shot shared by The Saturdays singer on Instagram as Tadgh turned five weeks old.
