Paris Hilton didn't wear underwear to her birthday party on Saturday (15.02.14).
The socialite and businesswoman celebrates turning 33 today (17.02.14) but held a party this weekend at Greystone Manor in Hollywood, and arrived at the event in a pink gown by Alon Livne which was slit so high on the thigh, it would have revealed the band of any undergarment.
Explaining her fashion choice, she wrote on Instagram: "Love my beautiful #Birthday dress! Thank you alonlivne! I feel like a princess!! "Yes! I know! My dress has a very high cut slit! And that's because it's a dress straight off the runway! I saw it in my friend @AlonLivne's #NYFW fashion show & I just knew it would be the perfect #Birthday dress! Loves it! #CoutureRunwayBarbie (sic)"
Paris - who is also an aspiring singer and DJ - also performed at the party, and was very impressed by the crowd's reaction. She wrote on Twitter: "#YES! #Killedit tonight with my set at @Greystone_Manor! Never seen LA rage so hard at an LA club! So happy you all loved my set so much! (sic)"
