Lady in red! Demi Lovato vamps it up in cleavage-baring cut-out dress matching scarlet lips for The Summer Spectacular event in LA

One of her biggest hits is Cool For The Summer, but on Saturday night Demi Lovato was red hot.

The 25-year-old Sorry, Not Sorry singer was a head turner in a short red dress on the red carpet for The Summer Spectacular event in Los Angeles. 

Lovato’s revealing frock featured a cutout that put her enviable cleavage on display for the high profile night out.
