Rihanna was the epitome of sophistication earlier in the day, but she turned heads with her dramatic transformation at her Halloween party on Wednesday evening. The pop star, 35, embraced a carnival queen theme, donning an eye-catching green outfit. She wore a sparkling green dress and a coordinating green veil, setting the tone for a glamorous and festive celebration at Greystones Manor in West Hollywood.

Arriving fashionably late with friends Evelyn Lozada and Shaniece Hairston, Rihanna showcased her commitment to the Halloween spirit. Evelyn Lozada opted for a vibrant red wig and dressed as Ariel from *The Little Mermaid*, while Shaniece Hairston went for a daring look in a revealing black dress and eye mask. Rihanna’s former boyfriend, Chris Brown, made a controversial appearance dressed as an armed Arab, which sparked mixed reactions.

Paris Hilton joined the festivities in a playful Robin costume, featuring a short green skirt, red bustier, yellow cape, and eye mask. Meanwhile, Lindsay Lohan arrived in a Top Gun-inspired outfit, keeping a low profile with her black pilot’s uniform and long hair. French fashion designer Christian Audigier and his model girlfriend Nathalie Sorensen also attended, sporting matching avant-garde black outfits and makeup.

Comedian Kevin Hart added a retro touch with a 1970s-themed costume, complete with a flared boiler suit, platform shoes, and an afro wig. Despite the eclectic mix of costumes, Rihanna’s green ensemble remained the standout feature of the evening. She later made a grand exit, still in her elaborate costume, as she left the party in high spirits.

Earlier in the day, Rihanna had a more understated appearance as she attended the West Hollywood Halloween Parade. Dressed in a sheer black top that revealed her bra and a form-fitting black skirt with fringing detail, she looked every bit the Queen of the parade. She was honored with the title and received the key to the city from Mayor John Duran. Her outfit, paired with sheer black pumps and a sparkling crystal crown, was a nod to her new royal status.

Rihanna’s Halloween festivities were a prelude to her upcoming *777 Tour*, where she will perform seven intimate gigs in seven different countries over seven nights. The tour, beginning November 14, will support her latest album, *Unapologetic*, her seventh release in as many years. The tour will see Rihanna and a select group of journalists, fans, and her team traveling on a Boeing 777, making stops in various international locations.

Notably absent from the parade and the party was Chris Brown, who instead attended the Supper Club’s Halloween Costume Freak Fest in Hollywood. Brown’s choice of a disheveled look in lemon skinny jeans and a leather jacket contrasted sharply with the glitz and glamour of Rihanna’s events.
