Katy Perry was all curves in a form-fitting polka dot dress after she left Radio 1 Studios following her appearance on the Scott Mills show in the UK.

The pop star recently talked about her Twitter loves and loathes.

She explained, "I started to follow Kanye West and then I unfollowed him; I think he's hilarious... but there's probably like 100 tweets for one golden one... I'm like, 'Kanye, calm down'. There was one tweet that he tweeted that I I retweeted - he said, 'I love me...' How many fingers do they have why do they have so much extra time. I follow M.I.A... she's got good pictures of her nails that she sends out sometimes."
