Demi Lovato used her singing skills for a new job on "The Late Late Show with James Corden". In a segment aired on Tuesday night, August 4, the former Disney star and the show's host drove around Los Angeles to deliver singing telegrams to the recipients.

Their first client was Sarah, an employee of salon Dry Bar who recently got promoted. "I don't know why they just don't call this place Blow Jobs," Lovato enthused. Learning that Sarah likes country music, Lovato put on her best southern accent while singing, "When it comes to blowin' people, Sarah has no fears."

On their way to visit the second place, Lovato and James Corden played "Cruise, Marry, Shag," an alternate version of "Kill, Shag, Marry." Given the choice of Tom Cruise, Mark Ruffalo and Hugh Jackman, Lovato chose to go on a cruise with Cruise. Corden chimed in, saying that he would marry Jackman and let Ruffalo "just go to town on me."

Upon meeting the second client, Cory, they sang a song about his love of mayonnaise to honor his birthday. The last visit was a dentist's office. They sang a tune honoring Dr. Engel who already raised $6,000 for his local YMCA.

The dentist promised to shave his head if he raised $10,000, so Lovato and Corden helped him reach his goal by donating $4,000. Corden then asked Dr. Engel if he would let Lovato shave his head before she grabbed a razor and shaved his head bald.

"That was...I don't think what anyone was thinking," Corden commented after they completed their task.
