Demi Lovato and James Corden drove around Los Angeles for a Late Late Show segment Tuesday, delivering singing telegrams to a few everyday heroes. The first stop: Dry Bar to commend Sarah on her recent promotion.
"I don't know why they just don't call this place Blow Jobs," Lovato, 23, joked.
"Yeah, or 'Blowies,'" said Corden, 36.
Once inside, Corden clapped to maintain beat, chiming in when necessary, and Lovato unleashed a spot-on Southern accent. "When it comes to blowin' people, Sarah has no fears," she sang with twang.
On the way to their next patron, Cory, the "Cool for the Summer" singer and late-night host entertained themselves by playing a game of "Cruise, Marry, Shag."
Given the star-studded lineup of Tom Cruise, Mark Ruffalo and Hugh Jackman, Lovato said "you have to" go on a cruise with Cruise. Corden completely agreed and explained he would marry Jackman and let Ruffalo "just go to town on me."
"Do you like it Ruffalo?" Lovato mused.
After singing a jingle about mayonnaise to Cory for his birthday, Lovato and Corden headed to their last stop: Dr. Engel's dentistry office. The twosome explained that the dentist has been raising money for the YMCA and learned that he would shave his head if he reached his goal of $10,000. Needless to say, the stars had no problem helping him out, and Lovato shaved his head completely.
"We might be the world's first singing telegram, mobile barbers, am I wrong?" Corden said. There is a business here, Lovato."
The Late Late Show airs weeknights at 12:37 a.m. on CBS.
