The 22-year-old beauty has been holidaying with the entrepreneur, and posted a picture to her Instagram account of the pair holding hands as they dined at the Flying Fishbone Restaurant in Aruba.

Amy captioned the photograph: "Beautiful dinner at the @flyingfishbones tonight !! Eating 'unicorn fish' on the water with my unicorn @robg2208 #ARUBA. (sic)"

Amy and Rob also attended parties during BRITs week, chilled with reality star Scott Disick in Las Vegas and hung out at Coachella Valley Music and Arts Festival in California.

A source told the Daily Mirror newspaper: "They recently made it official."

Amy previously dated former 'The Only Way Is Essex' star Joey Essex - whose ex-fiancee Sam Faiers recently confessed she "lost the plot" when they began dating in the 'I'm A Celebrity...Get Me Out Of Here!' jungle - and also enjoyed secret dates with Niall Horan.

The One Direction star was reported to have started seeing the British model and former Miss Universe contestant - who ranked in the top 20 in FHM's latest 100 sexiest women in the world list - behind closed doors after they met in December last year but the pair were said to be desperate to keep their friendship "under wraps".

A source said previously: "Niall and Amy have done well to keep their friendship under wraps.

"They're private people and don't want to highlight their celebrity friends where possible. Plus it would set tongues wagging about a relationship."

It is believed the 'Night Changes' hitmaker and the 'I'm A Celebrity...Get Me Out of Here' star stayed in contact while One Direction embarked on their 'On The Road Again' world tour but never discussed whether their secret romance would blossom.
