The Avengers might have welcomed Elizabeth Olsen with open arms, but the Scarlet Witch actress just recently revealed that Taylor Swift did not exactly invite her to join her super famous girl posse. 

Elizabeth Olsen, the younger sister of Full House actors and twins Mary-Kate Olsen and Ashley Olsen dished about an awkward encounter she had with the "Welcome to New York" singer at a mutual friend's birthday party while on "The Late Late Show With James Corden."

Asked about Swift, Elizabeth Olsen gushed and said that she extremely loves her. In fact, the Avengers beauty said that she used Swift's song for her dance sequence in her ballet class and only listens to her songs when she is working out.

The 26-year old actress also said that she talked with Swift for quite some time, which makes her think she blew it because they "didn't exchange phone numbers or anything."

Well, Elizabeth Olsen, also called Lizzie, might not be getting late-night updates from Swift, who counts celebrities such as Selena Gomez, Ella Yelich-O'Connor aka Lorde, Lena Dunham, Karlie Kloss and Sarah Hyland as girl friends, because she unintentionally dissed one of the world's biggest pop star's music. 

At one point during their awkward encounter, Elizabeth Olsen shared that Swift asked her which song it was she used. Unfortunately, the Avengers star could not remember what the title was and she didn't want to sing it for her.

"I am still nervous thinking about it right now," she added.

And while things didn't work out with Swift, it's good that the actress is comfortable with her co-stars in the blockbuster Avengers movie "Avengers: Age of Ultron."

When James asked her to reveal who the biggest diva on the Avengers set was, Elizabeth Olsen quickly responded, "No one's a diva, but...," and the host immediately jumped in to rephrase the question.

"Who takes the most time in the makeup chair?" the host said.

To which, Elizabeth Olsen replied with "Thor" and explained that it is because the Avengers hunk has a lot of hair and needs to put so much body makeup on.

Meanwhile, Us Weekly claimed that Elizabeth Olsen is getting extremely cozy with Tom Hiddleston, who portrays Loki. Though they have not been in the same Avengers movie together, a source revealed that the two have been hooking up.
