Transformers: Age of Extinction actor, Jack Reynor is engaged to his girlfriend, Madeline Mulqueen.

According to E! News, the 22-year-old actor popped the question to his Dublin-based model girlfriend after a little over a year of dating.

The couple went public with their relationship in February of last year at the Irish Film and Television Awards after flirting on Twitter.

Reynor and Mulqueen have been inseparable since and the 22-year-old model even moved to Los Angeles with her beau while he was busy filming the newest installment of Transformers, according to Daily Mail.

“We had a house in LA. It was good that we were together and experiencing it together,” Mulqueen commented.

Meanwhile, Reynor showed his affection for his sweetheart, calling her the ‘best girlfriend in the world’ alongside a Twitter photo of his Valentine’s gift – a copy of Richard Harris’s biography of A Man Called Harris.

"Amazing Valentine's Day present from the best girlfriend in the world. @MadelineMul #luckymotherf--cker," he tweeted.

The rising Irish actor is also set to receive the Rising Star of 2014 Awards later this month in Las Vegas at CinemaCon.
