TV Article Demi Lovato and James Corden deliver singing telegrams By Jessica Goodman Published on August 5, 2015 11:59AM EDT Demi Lovato wants to make sure you’re extra cool for the summer (har har), so she went around delivering singing telegrams with James Corden on The Late Late Show. Wearing matching outfits, the two stopped at Drybar to make some double-entendre jokes about blow-drying, celebrated mayo-loving Cory’s 25th birthday, and visited a dentist’s office (where Lovato shaved the dentist’s head). Lovato has been teasing her “badass” forthcoming new album all summer, but her latest single, “Cool For The Summer,” is the only track available so far. It’s doubtful the risque Drybar duet will make on the record, but fingers crossed it’s one of her b-sides. •Demi Lovato drops infectious new track, ‘Cool For The Summer’ •Demi Lovato explains how she’s like Nicki Minaj & Rihanna •Demi Lovato wipes out on stage, laughs it off as ‘not cool for the summer’
