And it's freaking hilarious!
Ch-ch-check out the brutal bit (above)!
Since she's been busy doing costume changes at Disneyland, reading mean tweets on Jimmy Kimmel, and prepping for her big Saturday Night Live gig, it's no surprise she has to fuel up to get it all done.
And fuel up she did as Katy stepped out for some grub at Arlington Club Steakhouse and Sushi in NYC. But that wasn't all she ate up because her honey John Mayer added a touch of lovin' during the date night!
Katy and John were caught looking like a cutely casual twosome during the low-key dinner. We're not sure if they had dessert later - wink wink! - but we hope Katy got a good night sleep either way!
Even pop princesses need their beauty rest!
