Tom Cruise tends to remain private when it comes to his love life, leading to endless speculation about whom the A-list star is dating.

At the recent premiere for "Mission: Impossible - Dead Reckoning" in Rome, Cruise was spotted getting up close and personal with two co-stars, illustrating his affectionate nature on the red carpet.

First photographers snapped photos of Cruise hugging Hayley Atwell during a cocktail party at the hotel De Russie in Rome before the world premiere of the film.

There had been rumors that Cruise was dating Atwell, a relationship that allegedly began in 2020 while filming the latest installment in the "Mission: Impossible" franchise.

However, the actors never commented on their rumored romance, and Atwell announced she was engaged to her boyfriend, Ned Wolfgang Kelly, in April.

On the red carpet the next day, Cruise also appeared affectionate with his other co-star, Rebecca Ferguson. He gave her a kiss on the cheek, and she seemed to whisper in his ear. They held onto each other for several photos.

Despite the cozy appearance, Ferguson is married to businessman Rory St. Clair Gainer, with whom she has one child.

During the press tour for 2017's "The Mummy," the actor was rumored to be dating co-star Sofia Boutella. At a stop in Sydney, Cruise gave her a kiss on the cheek, and she had her arm around him at one point.

Rumors flew across the internet that the two were an item, but it amounted to nothing more than speculation.

Simply being in the same proximity as another beautiful star can get people talking about the Oscar-nominated actor's love life.

At last month's Miami Formula One Grand Prix race, the "Top Gun" star was photographed walking with Shakira below the thousands of attendees in the stands.

The rumor mill quickly began grinding out headlines, but the recently divorced Shakira shut down the story shortly after the photo was taken.

In a report by Us Weekly, a source told the outlet, "Shakira had a great time hanging out with Tom at F1, but she has no interest in dating him. He was really nice, and she enjoyed his company, but she isn’t focused on dating him or anybody else at the moment. She has a lot on her plate and is focused on her kids and career for now."

'TOP GUN: MAVERICK' STAR TOM CRUISE ADMITS HE 'CRIED' OVER 'EMOTIONAL' REUNION WITH CO-STAR VAL KILMER

At the "Top Gun: Maverick" premiere in London, Cruise held Princess of Wales Kate Middleton's hand as he walked her down the red carpet.

The hand-holding raised some eyebrows as it appeared to be a breach in royal protocol. But according to the royal family's website, there are "no obligatory codes of behavior" when greeting a royal. There are traditional options, including "a neck bow (from the head only)" for men, and the website indicates that shaking hands with a royal is perfectly acceptable.

The now-Prince and Princess of Wales didn't seem to mind Cruise's gestures at all and could be seen laughing and chatting with the star throughout the evening.

And for once, the actor's interactions didn't generate dating headlines, seeing as Middleton is happily married to the heir to the British throne, Prince William.

While Cruise's gestures often spark romance rumors, when he is in an actual relationship, he makes that very clear on the red carpet.

His first marriage to actress Mimi Rogers lasted from 1987 to 1990. In a Rolling Stone interview, Cruise revealed how they met, saying, "I met her at a dinner party about a year ago, when I was developing ‘Top Gun.’ She was dating a friend, and, uh, I thought she was extremely bright."

While walking red carpets, Cruise could be seen holding Rogers' hand and sticking close to her at every event they attended together.

After his split with Rogers, Cruise married Nicole Kidman. The couple starred in three movies together, "Days of Thunder," "Far and Away" and "Eyes Wide Shut," and were a staple on the red carpet throughout the '90s. 

In a 1994 Vanity Fair interview, Cruise said of the relationship, "It was that special connection when you recognize your soulmate. She is a person who understands. It was as if a whole new life had started for me."

During their time together, Cruise appeared more comfortable showing affection at events with Kidman, not just holding her hand but hugging and holding her close.

The couple, who share two adopted children, divorced in 2001 after 11 years of marriage.

Not long after his divorce from Kidman, Cruise began dating his "Vanilla Sky" co-star Penelope Cruz.

Cruise's spokesperson, Pat Kingsley, confirmed they were an official couple, telling reporters in 2001," Tom Cruise invited Penelope Cruz to his 39th birthday party on July 6, and they've had a few dates since."

The actor also opened up about the relationship in Marie Claire, telling the magazine in 2003, "I surprise Penelope with different things. She’ll come home, and I’ll have her favorite kind of food made, have a bath drawn. I like doing stuff like that. She likes my food, so I cook for her. It’s always the little things I like in a relationship."

There were hints of Cruise's grand gestures when the couple arrived together for the London premiere of "Vanilla Sky" in 2001, with Cruise hanging out of an open car door waving to fans, while Cruz rode inside.

Cruise's grandest gestures came when he was courting his third wife, Katie Holmes.

They began dating in 2005 and later welcomed their daughter, Suri Cruise, in 2006 before marrying in Italy that same year.

The "Magnolia" star infamously jumped on Oprah's couch, declaring his love for Holmes, and his red-carpet moves matched that excitement.

In 2005, they arrived to a "War of the Worlds" fan event on a motorcycle together, making a grand entrance for their relationship.

The relationship eventually ended, and Cruise and Holmes divorced in 2012.

Since the split, Cruise has been rumored to be with many different women and co-stars, but none have been confirmed by the star.
