Ana de Armas ended her romance with Tom Cruise because she allegedly felt 'uncomfortable' with his fast pace. 

The breakup was 'Ana's decision' a source told Us Weekly on Thursday. Cruise, 63, and de Armas, 37, quietly split several weeks ago after nine months.

'Things were moving fast and she started to get a little uncomfortable with how fast it was going,' the insider shared.

The Ballerina star 'put the brakes on' but 'still likes [Cruise] a lot' the source added, sharing the two have 'undeniable chemistry'. 

Though they are 'done for now' the two 'have a connection' and 'they will see how things go in the future'. 

The Daily Mail has reached out to representatives for de Armas and Cruise for comment.

'They want to remain friends, but she needed to take a step back,' the insider further clarified. 

Their romance reportedly started after they 'spent every day together' while 'training for the intense underwater sequences' for their thriller Deeper, which is now on hold.

'It started as a deep professional respect and then it ignited. Tom was completely captivated by Ana,' the source went on.

Meanwhile de Armas 'enjoyed his company' and thought he was 'fun to be with'.

She was also 'attracted' to the fact that he 'supported her and everything she wanted to do'.

It comes following reports that de Armas has been 'in a funk' following the split and their film being put on hold.

'Ana thought this year would be very different so she is disappointed,' a source told the Daily Mail.

'But she knows it will get better and is plugging on. And she is still friends with Tom. She is not crying at home,' they added.

News of their split broke earlier this month.

A source close to the pair told The Sun: 'Tom and Ana had a good time together but their time as a couple has run its course.

'They are going to remain good friends but they aren't dating anymore. They just realized they weren't going to go the distance and that they are better off as mates.

'The spark had gone between them but they still love each other's company and they've both been really adult about it. She's already been cast in his next film, so they will continue to work together.'

Tom and Ana were last publicly seen together months earlier in July as the pair went official with their budding romance.

At the time, the two stars were seen holding hands as they whisked themselves on a weekend getaway to Woodstock, Vermont.

They were spotted strolling through the scenic town together - after first sparking relationship speculation earlier this year in February.

Shortly before the Vermont trip, both stars were also seen attending the Oasis concert at Wembley Stadium.

That same month, Tom and Ana also enjoyed a boat day while on a getaway to Menorca, Spain.

'Tom has been showering Ana with gifts ever since they met, it's his thing, he is thoughtful,' a source exclusively told the Daily Mail in July.

'First it started with her favorite flowers then books he thought she would want to read because she's an avid reader.'

The insider added, 'The more they got to know each other, the bigger the gifts became. There has been jewelry like gold bracelets and designer clothing, things like that, things every girl would love.

'Probably the biggest gift he has given her is being able to go anywhere in the world at a moment's notice, not many people can do that. She loves to travel.'

The Hollywood stars first ignited romance rumors when they were spotted grabbing dinner in London just before Valentine's Day.

The pair were seen on more than one occasion in the following months, such as Ana and Tom dining at a restaurant in London.

In May, they attended David Beckham's 50th birthday bash which was held in Notting Hill - and left in the same vehicle together.

However, a guest who had also been in attendance at the time told Page Six that Ana and Tom's relationship appeared to be platonic.

The insider explained that Tom and Ana 'came together and had a great night and clearly enjoy hanging out'.

However, they added, 'But I couldn't say any more than that... I've no proof it's romantic.'

A separate source informed Us Weekly at the time that the Top Gun: Maverick star was 'super smitten' with Ana.

It was then added the romance was 'low-key' and 'still new and in the early stages'.

The insider stated that both Ana and Tom first met back in February for work-related discussions, which then led to the 'relationship developing'.

'They've gone out on some dates and it's very low-key. It's in the early stages and he's been courting her.'

In September, the actress was seen partying with rapper Bad Bunny during a trip to Puerto Rico. At the time, the beauty filmed herself dancing to his hit song NUEVAYoL while at the music artist's concert.

And earlier this month, Ana was also seen posing with a mystery man during Paris Fashion Week. While exploring the French city, the star posed for a lighthearted Instagram snap with two pals as they spent time outdoors.
