Rumors that Elizabeth Olsen is purportedly daiting Tom Hiddleston have been circulating for weeks now.

However, there have also been insider tips that Mary Kate and Ashley's younger sister has been going out with Chris Evans. So, what's the real score between the "Avengers" co-stars?

Are Tom Hiddleston and Chris Evans involved in a competition in trying to win the heart of Elizabeth Olsen?

Elizabeth Olsen may have been getting close to Chris Evans in July when an insider dished out that they've been keeping an alleged low profile affair.

"Chris and Lizzie are definitely involved in some kind of ultra-secret romance that's being kept under wraps while they shoot," an insider source told The National Enquirer, quoted by Hollywood Life. "The attraction between them has been there from day one."

It has been reported then that the Captain America actor allegedly wanted to keep their dating status private for the sake of his career.

"Chris is paranoid about his womanizing becoming public while he's on this multi-picture deal with Marvel," the insider added. "He's protecting his image, and will bend over backwards to keep things quiet."

Did Chris Evans' desire to keep his relationship with Elizabeth Olsen a secret give Tom Hiddleston a chance to make a move on the "Avengers" actress?

Only two weeks after Elizabeth Olsen and Chris Evans' alleged secret affair has been reported, an insider revealed that Tom Hiddleston may have been getting closer to the Lizzie.

"They've been talking constantly," an insider told Us Weekly about the "Avengers" co-stars. "It's been good for the both of them, they really care for each other."

"Neither of them are looking to jump into a large commitment, but it's getting more serious."

Bustle recounted that before being linked to her "Avengers" co-stars, Elizabeth Olsen has been dated and got engaged to Boyd Holbrook before they broke up in January 2015.
