Lea Michele and Idina Menzel have bumped into each other on Saturday, Sept. 24.

In a video the “Scream Queens” actress shared on Twitter, Michele revealed that she and Menzel — who were both on their way to the 2016 iHeartRadio Music Festival — happened to be on the same plane heading to Las Vegas.

“Guess who’s on my plane,” Michele says at the beginning of the clip as she moves the camera to Menzel. “We’re here on our way to Vegas. Twins.”

Menzel played Shelby Corcoran on “Glee.” Shelby is the mother of Michele’s character Rachel Berry. Due to Menzel and Michele’s resemblance, a lot of fans thought that casting Menzel as Michele’s onscreen mom was perfect.

“@msleamichele … you look so much like Idina Menzel on some pics! I can see why her character is Rachel's mother :D” a fan tweeted earlier this month, to which Michele replied: “Haha I totally see it too! @idinamenzel you are the most beautiful!”

“It’s unclear whether the two have known each other before starring on the FOX musical dramedy, but the two definitely had become closer while working on the show together.”

“Me and @idinamenzel on set having the best day ever:) #Glee,” Michele tweeted back in 2013, along with a pic of her with the Tony nominated actress.

In the final and sixth season of “Glee,” Michele also had the chance to cover Menzel’s smash hit “Let It Go,” and the “Frozen” voice actress found it “stunning.”

Menzel is currently busy promoting her self-titled fifth studio album, which has just been released on Friday, Sept. 23. Menzel said that the album is the “most personal, introspective album” she’s ever made.

Michele, on the other hand, is hard at work reprising her role as Hester in “Scream Queens” Season 2, which premiered earlier this week. “Scream Queens” Season 2, episode 2 “Warts and All” airs on Tuesday, Sept. 27,  at 9 p.m. on FOX.
