Brad Pitt and Emily Ratajkowski are thought to be getting closer.

The "Once Upon a Time in Hollywood" actor and the supermodel-turned-author are said to have started dating recently.

A source told Page Six, however, that the purported pair is not formally dating.

They have been spending time together, according to the insider, especially since Emily's divorce from her husband, Sebastian Bear-McClard.

Despite being observed multiple times, the source noted that they had been seen with other persons.

Brad is also reported to be single, but a Hollywood insider cryptically added, "Stay tuned," amid reports that Brad Pitt and Emily Ratajkowski are secretly dating.

A source told OK magazine in August that the "Bullet Train" actor asked the model out, and she said yes.

Emily allegedly stated that she felt Brad was "attractive" and that she had nothing to lose because they were both unmarried.

Brad is currently going through the divorce process with Angelina Jolie, while Emily is still divorcing her 41-year-old husband after he reportedly cheated on her.

But, is there another reason Brad isn't officially dating Emily?

Brad Pitt Invited This Actress Overseas?

According to Woman's Day, Brad Pitt and Jennifer Aniston reconciled during the Venice Film Festival.

Their source revealed that the "Ocean's Eleven" star offered the blonde beauty to accompany him abroad, and she supposedly accepted.

Brad was also said to have surprised his ex-wife with a romantic date and everything in between.

The unnamed insider revealed that the A-lister actor is notorious for making lavish gestures to his current and future lovers "or a no-expense-spared vacation."

The tabloid also posted other images of the ex-lovers traveling the plane together, giving the impression that they were reunited.

However, this allegation should be treated with caution because there is no proof that Brad and Jennifer were together or that Brad flew his ex-wife overseas.

Jennifer, on the other hand, was recently entangled into a fresh issue involving Brad and Angelina Jolie, when the latter was accused of tipping off the paparazzi about where she and Brad were years ago.

Jennifer and Brad were still legally married at the moment, although they were on the verge of divorce but were still formally married.

The "Maleficent" actress has also been on the receiving end of hate as she is said to be the reason to have ended the marriage of the "Friends" actress and Brad.
