She managed to bag quite possibly the biggest celebrity philanderer the world has ever known and turn him into a loyal, faithful husband who only has eyes for her, so who am I to turn my nose up at celebrity beauty tips from Katy Perry, right?
This lady also happens to be named Maxim's sexiest lady in the world, and like many of us, there's no denying she had to use a few products to get there.
Thankfully she's revealed some of her top must-haves, and I have to confess, they're automatically being coped and pasted into my Christmas wishlist... in case you're still wondering what to get me.
She uses Dior's DiorShow mascara in Azure Blue to make the blue in her eyes pop, while adding MAC's 30 false lashes to get extra stunning peepers.
Paying attention to detail, she uses Dashing Diva's Design Nails On The Go, and says: "I keep a pack in my purse at all times. They take less than five minutes to put on."
Katy uses ProActiv to keep her troublesome skin at bay, and covers up with Vichy's Dermablend Corrective Foundation in Opal.
Ole Henriksen's African Red Tea Exfoliating Lip Salvation is also another staple for the singer. "I use lip scrub every night, so when I wake up, my lips don't feel like they've been on desert island," explains Katy.
