Rihanna dazzles at Fenty Beauty launch in London

Sept. 20 (UPI) -- Rihanna dazzled on the red carpet at the Fenty Beauty launch in London.

The 29-year-old American singer and designer introduced her cosmetics line to British fans Tuesday at Harvey Nichols Knightsbridge amid London Fashion Week.

Rihanna stunned in a lilac-colored Molly Goddard minidress, diamond jewelry and strappy stiletto sandals. She complemented her look by wearing eyeshadow, blush and lipgloss with a purple sheen.

"Thank you to my U.K. team at @harveynicols for a tremendous launch! I'm honored to have @fentybeauty in your stores!" she wrote on Instagram.

Rihanna previously launched Fenty Beauty in New York during New York Fashion Week. She discussed her line in an interview with The Sunday Times published this month, calling makeup "a lifelong obsession."

"Fenty Beauty is for everyone -- all skin tones and races," the star told the publication. "It's also for any occasion and any age."

"I used to watch my mom put her makeup on -- all the funny faces she'd make in the mirror," she recalled. "I never understood what she was doing, until I got older and fell in love with makeup myself."
