The celebrity pairing of Tom Cruise and Ana de Armas continues to generate headlines. Just one day before the acclaimed actress' 37th birthday, the duo were photographed disembarking a helicopter in London, with Cruise, 62, at the controls. This sighting follows several other public appearances together in recent weeks, fueling speculation about their relationship. Images obtained by TMZ show de Armas, wearing a casual hoodie and shorts, exiting the helicopter with one of her dogs. Cruise, dressed in a dark T-shirt and jeans, followed after a brief interaction with airport staff. A second dog was seen leaving the helicopter on a leash held by another individual. While the proximity and repeated sightings suggest a close connection, a source close to the situation tells PEOPLE that the relationship between Cruise and de Armas is purely professional. They are reportedly collaborating on an upcoming, yet-to-be-announced project. The source added that any birthday celebrations were likely 'maybe' a joint affair. This helicopter ride isn't the first time the pair have been seen together in London. Earlier this month, they were spotted arriving in the city via helicopter, alongside director Doug Liman, who previously worked with Cruise on *Edge of Tomorrow* and *American Made*. The nature of their collaboration remains undisclosed. The pair's repeated public appearances together, however, haven't gone unnoticed. Their February dinner date, where sources say they were discussing potential collaborations with their agents, only served to further fuel speculation of a romantic relationship. Despite efforts to keep their association primarily professional, the public continues to speculate about the true nature of their bond. De Armas, whose recent Oscar nomination for her portrayal of Marilyn Monroe was met with considerable acclaim, has previously spoken positively about Cruise. In a 2023 interview with USA Today, she described his stunt work as 'mind-blowing'. Cruise is currently promoting the upcoming release of *Mission: Impossible – Dead Reckoning Part One*, the eighth installment in the iconic action franchise. While the mystery surrounding the exact nature of Cruise and de Armas' relationship continues, one thing is certain: their frequent public appearances together guarantee that the speculation will persist for some time to come. PEOPLE has reached out to representatives for both actors for comment but has yet to receive a response.
