The new Marvel Cinematic Universe film, "Avengers: Age of Ultron," added a few new characters to the team of Earth's mightiest heroes, including Scarlet Witch, played by the younger sister of the Olsen twins - and as all eyes are now on the young star, it seems like Elizabeth Olsen's dating Tom Hiddleston!

In the past, Elizabeth Olsen's dating life has become subject of news, as the 26 year-old star was engaged to her "Very Good Girls" co-star, Boyd Holbrook, until last January; now, one of the younger members of the Olsen household is making headlines once again by going out with one of the biggest stars of the MCU.

According to Perez Hilton, rumors that Elizabeth Olsen is dating Tom Hiddleston surfaced earlier this week, as word has it they clicked during the shoot of their newest film, "I Saw the Light," a musical where they play a married couple.

Besides the fact that they make a beautiful couple, fans are going crazy with Elizabeth Olsen's dating rumors as it might mean the first couple formed from the MCU, as she plays new Avenger Scarlet Witch and he's been playing Thor's adopted brother, Loki, since 2011.

"They have been hooking up," a source close to Elizabeth Olsen's dating life told Us Weekly, saying that, while their relationship is fairly "casual," it doesn't keep them away from texting when they're away from each other.

It seems like the two Marvel stars have been friends for a while, but had kept their distance romantically due to Olsen's relationship with Holbrook - but a few months after their engagement ended, there's nothing to stop them!

Mid-Day reports that, in the past, Hiddleston had been romantically linked to record producer Jane Arthy, though the actor is famously private about his personal life.

Good luck to the two stars now that Elizabeth Olsen's dating Tom Hiddleston!
