Keanu Reeves and Sandra Bullock have apparent onscreen chemistry. But, this is reportedly not an act as they have feelings for each other.

Sources told OK! magazine for its March 7 issue that close friends of the two celebrities are even "holding out hope" for a romantic relationship between them. As alleged, many people think that it is "written in the stars" for them to wind up together.

Bullock and Reeves are said to be a "perfect match," adding that it frustrates individuals as they have refused to act on it. Although they would "never cheat" on Bryan Randall and Alexandra Grant, respectively, there is allegedly a reason why the "Speed" lead stars have failed to make things official with their current partners.

The insiders insisted that Sandra Bullock and Keanu Reeves are "holding off," so they could "explore their connection" if they end up single.

Despite all the claims, though, no proof has come to light to prove the latest story about the two veteran actors. Although they themselves have not released any comment on the matter, their reps reportedly dismissed the allegations.

The outlet revealed that the duo's respective representatives deny Reeves and Bullock have romantic feelings for each other. But, the same informant argued that "The Lake House" lead stars are eager to spend time together.

Whatever the case, though, this remains a rumor and likely a misleading narrative. The two stars have, indeed, confessed about crushing on each other in the past, but they have emphasized, as well, the value of their friendship to date.

Sandra Bullock even told Ellen DeGeneres in 2018 that they are "probably friends for that long" because they did not give their feelings for each other a try, according to Cheat Sheet. It was in the same interview that she confessed about her huge crush on Keanu Reeves while working for their first film, "Speed," together.

These days, it is unclear whether the onscreen couple have continued to hang out or catch up. But, over the years, both of them have shared about talking to each other and spending time together from time to time.

Sandra Bullock and Keanu Reeves have, also, previously expressed interest in working together again on the big screens. The actress even joked about making the "bookend of 'Speed'" with the latter as she would love "nothing more than to do a comedy with Keanu" before they die, as per Insider.
