Billi posted the picture on her Instagram page with the caption: 'Little Family #MyBoys #MyEverything.'

The 27-year-old seems to be slipping easily into the role of the proud mother as she has flooded her account with pictures of her tot.

She posted another 'selfie' cuddled up to her newborn son with the caption: 'Love My Little Man So Much #MyBoy #10DaysOld.'

Wearing a white tank top and a delicate silver heart necklace, she looked stunning with her blonde hair curled into loose waves.

The couple have not been able to contain their delight at welcoming him into the world - announcing his birth almost instantly on Twitter, just hours after his birth last week.

Andy, who already has two children from a previous relationship, Emilie Rose, five, and son Lucas, three, has graced his second son with his middle name, Thomas,

The pair even share the same initials much to Billi's obvious delight, as she posted a cute photo of father and son leaving the hospital together, referring to them as 'Big AC and Little AC'.

Little AC even managed to surprise his dad on Father's Day, with Billi making sure the newborn's name was emblazoned across a balloon and presents for Andy.

With a stack of presents displaying his tiny stature for all to see, Billi had little Arlo propped in bed on Sunday with a stack of goodies and sweet surprises.

Andy and Billi got engaged last November after he whisked her off to Rome for a surprise birthday weekend.

While Billi broke the news of her pregnancy on Christmas Day in 2014 by donning a festive jumper with the words 'making my little pudding', subsequently posting the photo to social media.

The blonde beauty left TOWIE in 2013 to focus on her Bikram yoga studio, her second business after running Beaus & Belles beauty salon.
