Rihanna bared her bum in a see-through skirt while supporting her boyfriend, A$AP Rocky, at Rolling Loud in Los Angeles.

The Savage X Fenty founder wore a navy blue bomber jacket and a sheer lace maxi skirt — with her black underwear peeking through — for the music festival at Hollywood Park in Inglewood, Calif., on Saturday.

She accessorized with a diamond choker and black strappy heels.

Rihanna, 37, styled her hair in a long bob and put on a nude-brown lip for the nighttime outing.

Beyoncé and Jay-Z’s 13-year-old daughter, Blue Ivy Carter, also attended the “Fashion Killa” rapper’s performance, per a video shared on X.

Rocky — who headlined the hip-hop music festival — started his set with a clip about his recent trial after being accused of shooting bandmate A$AP Relli in 2021, according to Complex.

Rocky, 36, was found not guilty of the shooting in February.

He made his grand debut onto the Rolling Loud stage by descending from a helicopter.

He then dedicated his performance to immigrants and the victims of the Los Angeles wildfires.

The Fenty Beauty founder, meanwhile, has recently stepped out wearing body-baring ensembles.

Last week, she attended a Fenty x Puma event in her native Barbados, donning a neon bikini top from Heavy Manners ($110) underneath a green see-through top and baseball jersey.

Rihanna completed the head-turning ensemble with a green tutu.

In January, she played cupid for Savage x Fenty’s Valentine’s Day campaign.

The “Diamonds” singer posed in lacy red lingerie, including a red sheer bra with hearts, matching underwear and a garter belt.

She also turned up the heat for Savage X Fenty’s collaboration with Diesel in October 2024. At the time, Rihanna rocked a fishnet bustier set.
