She is in Paris for its Fashion Week to attend the runaway shows and no doubt look for some inspiration for her own wardrobe.

But Katy Perry is also one to set her own fashion trends, and in this case, the sexier the better.

The pop star was snapped in the French capital today in two very eye-catching outfits that left very little to the imagination.

She was first seen in an outfit that showed off her underwear to the world as she left the Hyatt Hotel in a mint green outfit that flashed her pert derriere through the sheer chiffon skirt.

The knickers rode up revealing probably a little more than she was hoping as she left the hotel surrounded by her security.

She teamed the outfit with towering Christian Louboutin strappy cream heels, a salmon pink handbag and white rimmed sunglasses.

And later on, she arrived back at her hotel for a quick change, and we mean quick, judging by the size of the dress.

The 27-year-old came back out in a very short and very tight gold patterned dress which had a very plunging neckline.

Her blue bobbed hair looked more shiny as she tottered out in the same heels but a gold clutch bag replacing the pink one from earlier.

She was heading to the Invalides Place to meet some friends before to go at La Maison du Caviar for a party.

Katy arrived in the city yesterday for its Fashion Week which starts today although of all the places in the world to visit, the city of love probably isn't the best choice for somebody going through a divorce.

So perhaps that's why she looked rather glum as she arrived at Paris-Charles de Gaulle Airport yesterday evening.

Speculation had surrounded the singer's new single Part of Me, which she performed at the Grammys and appeared to be about estranged husband Russell Brand.

With lyrics like, 'You can keep the diamond ring - it don't mean nothing anyway,' many people believed that the song was aimed at the British comedian.

However, the 27-year-old has insisted that the track was written years before she even married Russell and their on going divorce proceedings have nothing to do with the song, despite their obvious relevance.

Katy said: 'I wrote Part of Me two years ago and I always knew that Part of Me was a special song.

'It feels like my life plays out with these songs. I feel like I'm in some kind of weird 'Truman Show' where I'm like, 'Why is this single appropriate now and it wouldn't have been appropriate then?' It's just so crazy.'

The blue-haired star added: 'I guess the universe is kind of - we're kind of like, dancing together in some weird way.

'Does that make sense or am I being too hippie? I think it's really important for me to write songs that are still honest and relatable because that's what everyone else is going through.'

Her new song debuted during her performance at the Grammy Awards last month and it went straight to number one on the Billboard charts.

It was produced by Dr. Luke and mostly written by Bonnie McKee whom both were at the helm for her other chart toppers including California Gurls, Teenage Dream, and Last Friday Night (T.G.I.F.).

The breakup anthem should help the star get over Russell, who is reportedly dating Mexican artist Oriela Medellin Amieiro, and her friends are encouraging her to get back in the saddle.

A source told HollywoodLife.com: 'Katy has been very upset about the divorce.

'She never expected it to end and now she’s dealing with the aftermath.

'But her friends are telling her to get back out there and date. They don’t want her to waste time being upset over Russell.'

While those close to her are looking at her immediate future, Katy has already imagined her life as a pensioner.

She told Interview magazine: ‘I feel like I could be in Florida on a kind of healthy trip where I’m just riding my bike and chillin’ at the beach, with an assisted-living condo bit and a meal delivery service—which is sort of how I’m living now. But I also kind of hope that I turn out to be like my grandma, who is 91 and so rad.’

The star also discussed how different she is from the rest of her family.

She said: ‘I think they just see that the dynamic has changed because I’m in a different place. But it’s not like I disrespect them in any way. I mean, I take care of them. But that’s what I’ve always wanted: to have enough that I could make sure that everyone in my family had enough. I grew up not really having anything, so the idea that I can take care of my family and my friends now is a really cool bonus.’
