I've always said Ava Max has a very old school Lady Gaga vibe to her. What better place than Youtube to pick up on that as well. Not only does this mash up bring Ava Max and Gaga together but they've also tied in Taylor Swift and P!nk. This is it. And all these songs fit together perfectly. 'Sweet But Psycho', 'Bad Romance', 'Look What You Made Me Do' and 'Please Don't Leave Me' all in one. Really makes you wonder what would happen if all four women came together and put a real song out. Kick off your 2019 with a solid mash up below.
