Rihanna was last night's queen of the annual West Hollywood Halloween Carnaval. The singer was awarded a crown and a key to the city by the mayor at Greystone Manor nightclub, before heading inside to host an All Hallows' Eve bash with famous friends including Flo Rida and Paris Hilton. Rihanna skipped a costume for the festivities, instead opting for a black dress and heels, but was happy to pose with fellow partyers in their full regalia.

Rihanna took the night off work to focus on revelry, but the pop star isn't slowing down on the career front any time soon. This week, she announced that she's planning what she calls her 777 tour, where she'll play seven shows over seven days in seven different countries. The concert series kicks off mid-November, timed to the release of her upcoming studio album, Unapologetic. Rihanna also made headlines earlier this week when news that a special, limited-edition box set of Unapologetic will run fans $250.

Nicole Richie turns 31 today! It's been an eventful year for her.

Over the years, she's kept the company of friends like Jessica Alba, Jennifer Lopez, and the Kardashians. Click through to see them all — and happy birthday Nicole!

Paris Hilton shared an exciting afternoon on Cavallo Island off the coast of Italy with a mystery man yesterday. She wore a black cutout swimsuit while her male companion went shirtless. (Make sure to play our Shirtless Bracket!) The duo shared plenty of PDA, kissing, and hugging when they weren't splashing around in the water. It looks like Paris has already moved on after breaking up with boyfriend DJ Afrojack back in May.

Paris has been living it up this Summer, hopping from one sunny spot to the next. She was in Ibiza in mid-July and, after a stop back in the States, popped up in Saint-Tropez late last month. Paris wore a bikini during one beach day in the French city. She's since returned to Ibiza in recent days, and went water-skiing with friends before meeting up with her new man.

Bikini-clad Paris Hilton was the latest celebrity to grace the beaches of Saint-Tropez today. The French destination has been a hot spot for Hollywood stars this week including Rihanna and Leonardo DiCaprio. Paris has been working on her tan, but she also fit in some time to do a little shopping yesterday. While checking out the high-end shops in Cannes she ran into former basketball star Magic Johnson at Chanel. Paris kept her eyes shielded from the sun in a pair of tortoise shades, and you can win your favorite pair of Summer sunglasses, with $500 from Neiman Marcus, by simply filling out your PopSugar bikini bracket — be sure to enter before voting closes next Tuesday night!
