Alex Pettyfer is dating a model.

The 'Endless Love' star has struck up a relationship with Marloes Horst, who is the new face of Maybelline, after meeting her through mutual friends earlier this year.

Marloes' agent at Next Model Management told E! news: "Marloes and Alex have been together seriously for a few weeks now. They are very much a couple. They are really happy."

The couple took a trip to Disnleyland in California today (10.04.14) to mark Alex's 24th birthday, and the blonde stunner took the opportunity to make their romance public by sharing an adorable snap of them on Instagram.

She accompanied the photograph, which shows them hugging while gazing into the lens, with the simple, yet adorable, caption: "Happy birthday baby".

Meanwhile, the hunky star - who famously has 'Thank You' tattooed above his crotch - recently claimed he was one of the last chivalrous men left in the modern world.

He said previously: "I'm a hopeless romantic, I say very loudly and proudly. I get a lot of stick for it.

"We live in a world where it's so accessible to date now, which is great. I don't judge that. We have so many ways of meeting people.

Alex previously dated Emma Roberts, whom's initials are etched on his wrist, after meeting her on the set of 'Wild Child' back in 2010.

He then went on to date Dianna Agron from August 2010 until February 2011.
