Tom Cruise and Ana de Armas sparked curiosity after being spotted together on multiple occasions in London, most recently on Wednesday, April 30 — the same day the *Blonde* actress celebrated her 37th birthday.

The two stars were seen walking casually through a park, chatting side by side while accompanied by security. Cruise wore a white T-shirt and jeans, while de Armas kept it simple in a light tee, jeans, and sneakers.

The sighting came just one day after they were photographed exiting a helicopter together, with Cruise, 62, reportedly at the controls.

Though the timing of their outings raised eyebrows, a source close to the pair told PEOPLE that there is “no romantic connection” between them and that their meetings are related to potential film collaborations.

This aligns with earlier reports from February when the duo was seen at dinner with their agents discussing future projects.

The pair, both experienced in action-packed roles, have crossed paths several times in recent months.

They were even seen arriving in London by helicopter in March alongside director Doug Liman, who has worked with Cruise on *Edge of Tomorrow* and *American Made*.

While the nature of their current collaboration remains undisclosed, speculation continues to swirl.

De Armas, set to star in *Ballerina*, a spin-off from the *John Wick* universe, has previously spoken about her admiration for Cruise’s stunt work.

Cruise, meanwhile, is preparing for the release of *Mission: Impossible – The Final Reckoning*, hitting theaters May 23.
