Witherspoon, Vergara lipsync Swift, Cyrus' hits

It seems like Reese Witherspoon has surely found a best friend in her "Hot Pursuit" co-star Sofia Vergara. The duo keeps sharing videos of themselves goofing around, lipsyncing popular songs by singers Taylor Swift and Miley Cyrus.

In between the film's promotion, the duo finds time to have some fun.

Vergara shared one video on Instagram on Sunday of her and Witherspoon pretending to sing Swift's "I knew you were trouble". Witherspoon perfectly mouthed every word to the song before the camera shifted its focus to Vergara, who screams "oh" with a man's voice, reports aceshowbiz.com.

Witherspoon shared the other video of them lipsyncing Cyrus' "Party in the U.S.A.". And similar to the "Trouble" video, Witherspoon sang the lyrics of the former Disney star's hit normally, before the "Modern Family" star tackled the "yeah" with a hilarious voice.

"Hot Pursuit" will release in US on May 8. It follows an inept police officer, played by Witherspoon, who must protect Vergara's character, a widow of a drug dealer, from criminals and dirty policemen.
