Transformers star Jack Reynor (22) stepped out with a stunning blonde in Las Vegas last night.
With his arm around the head-turning beauty, they made a handsome pair as they posed for pics on the red carpet of the Colosseum at Caesars Palace
But fiancee Madeline Mulqueen (23) needn't be worried – it was just his fellow Rising Star winner Nicola Peltz (19).
They co-star in upcoming movie Transformers: Age of Extinction and are already winning plaudits ahead of its nationwide release.
Looking a far cry from the low-budget movie actor he was a mere two years ago, Wicklow's Reynor made the effort to dress up for the occasion in a designer navy suit.
Nicola opted for a Saint Laurent sleeveless black dress teamed with Jimmy Choo heels.
The pair won the male and female Rising Star accolades in CinemaCon's Big Screen Achievement Awards (left).
IFTA-winner Reynor, whose big break came in What Richard Did, is also winning when it comes to his personal life. He recently confirmed that he's engaged to model and TV presenter Madeline Mulqueen.
The actor went down on bended knee recently and popped the question to the Horse Outside star, whom he has been dating for over two years.
The smitten pair have been inseparable since they first met over Twitter and travelled to the US together last summer.
Describing his sudden rise to success, Reynor said that "it's been mad."
"I couldn't even get an audition for network TV at home in Ireland. Now I'm talking about Vince Vaughn, Michael Bay and Mark Wahlberg like they're my mates."
