Katy Perry the grove tight dress meow extra russell brand

Looking very pretty in pink, a newly blonde Katy Perry made a special appearance at The Grove to launch her newest fragrance, MEOW!, in West Hollywood on Wednesday.

The posh mall was fully decked out in a pink winter wonderland for the sexy songstress, who signed autographs and posed for pix with fans that special ordered her sensual perfume, a sequel to, Purr.

Meanwhile the "Teenage Dream" singer received a bit of good news this week -- her hosting gig on SNL brought in the highest ratings since Nov. 5!

Looks like hubby Russell Brand's advice must've helped.

They should co-host an episode next time!
