Olivia Wilde is a proud mother of one and could someday have a second child with fiancé Jason Sudeikis. However, that day is not today. While rumors circulated that a second baby was on the way for the acting pair, Wilde took to Twitter to deny the rumors, but had some fun in doing it.

Wilde, 31, responded to an article in Star magazine that said she was pregnant and expecting another baby with 40-year-old Sudeikis. It was reported that she was covering up a baby bump at the premiere of HBO's "Vinyl" on Jan. 15. Wilde posted a tweet denying the report and saying the news outlet had her and Sudeikis "confused with someone else." You can see the tweet below:

Her tweet also joked that her bump was the result of burgers, which she expressed in an emoji. The Star article reported that a source said that her and Sudeikis "couldn't wait to become parents again" and that Wilde had been avoiding alcohol throughout the night of the event. 

The someone else Wilde was referring to was Emily Blunt and John Krasinski. According to E! Online, Blunt and Krasinski are now expecting their second child. The two have a one-year-old daughter named Hazel.

Wilde and Sudeikis started dating in November 2011. The couple then got engaged in January 2013 and they have a one-year-old son named Otis, who was born in April 2014.

Wilde will next be seen in HBO's music drama "Vinyl." The actress will play Devon Finestra, who is the wife of main character Richie Finestra (Bobby Cannavale). The show will tell the story of a 1970s music executive trying to make it during a time with lots of music diversity.

HBO's "Vinyl," which premieres Sunday, Feb. 14, on HBO at 9 p.m. EST
