The mum of three posted several snaps to her Instagram account, sharing her delight over the baby’s arrival.

Natasha and partner Mike Smith welcomed the bundle of joy but have yet to reveal their new son’s name.

Natasha shared one of the snaps with the caption: ‘I'm becoming a baby bore already and I don't care.'

She shared one remarkably cute picture of her newborn swaddled in a blanket with the caption: ‘Sooooo cute xx.’

Natasha delivered her third son 10 days after his due date.

The Celebrity Big Brother star tweeted a snap of her pregnant belly after passing her due date, obviously growing increasingly uncomfortable.

She shared it with the caption: ‘8 days over.... What's another 4??? #losingthewill.’

Natasha is already mum to two sons from her marriage to Ryan Giggs’ brother Rhodri, 7-year-old Louis and 12-year-old Liam.

She became a household name when it emerged that she had been having an affair with brother-in-law, footballer Ryan Giggs.

According to reports, Natasha had at one point become pregnant with his child but chose to abort the pregnancy.
