So much for a reunion. Katy Perry set flight for Indonesia this week, leaving soon-to-be ex-husband Russell Brand alone in Los Angeles -- and she looked hot doing it! Perry and Brand were rumored to be meeting up while Brand was in Los Angeles to promote his new show. Though their motives were different -- reports insist that Perry desperately wants to salvage the relationship, though Brand simply wished to hash out divorce details -- that plan looks to be nixed.

The 'Last Friday Night (T.G.I.F.)' singer hopped on a flight to Singapore, en route to a tour stop in Jakarta, Indonesia. Clad in a super short dress, gray heels and sunglasses with her shock of electric blue hair peeking out from beneath a floppy hat, we imagine the T.S.A. had very few issues with Perry -- though we can't imagine her getup will be comfortable enough for such a long flight!

Perry also sported an interesting accessory. If you look closely, you can see a ring on her wedding finger. Though it's not her wedding band, Perry's a savvy girl -- she knew anything on her left hand would raise questions and eyebrows.

In any case, Perry certainly stepped her airport game up. Seeing her dressed to the nines to board a morning flight certainly makes the rest of us stop and question if pajamas and Uggs are appropriate attire anymore!
