Cruise and de Armas Celebrate Birthday in London

London, England — Tom Cruise and Ana de Armas were spotted together on Wednesday, April 30, celebrating the actress’s 37th birthday. The pair enjoyed a stroll in a London park, one day after being photographed exiting a helicopter that Cruise piloted.

The actors were seen walking side by side, deep in conversation, while their security kept a close watch nearby. Cruise, 62, wore a simple white T-shirt and jeans, while de Armas sported a light-colored T-shirt, jeans, and white tennis shoes.

Witnesses reported that the couple appeared to be enjoying their time together, despite rumors suggesting they were only friends. A source told PEOPLE that they were “maybe” celebrating de Armas’s birthday together.

Photos released showed de Armas arriving at the helipad holding one of her two dogs, while Cruise was seen chatting with staff and giving a fist bump to one of them. The helicopter outing occurred after recent sightings of the duo together, including a dinner in February, where they were reportedly discussing potential collaborations.

Reps for both stars did not immediately respond to requests for comment. Previous interactions between the two suggest they are working on a project, although details of the collaboration remain undisclosed.

Ana de Armas is set to star in the upcoming action film, From the World of John Wick: Ballerina, which hits theaters on June 6. Meanwhile, Cruise will appear in the eighth installment of the Mission: Impossible franchise, titled Mission: Impossible – The Final Reckoning, releasing on May 23.

In a recent interview, de Armas praised Cruise’s impressive stunt work, highlighting her admiration for his dedication to action roles. She noted that while she admires his level of skill, she feels she is still on her journey to reach that level.
