Rihanna has reportedly asked Kate Moss to be her plus one when she performs at a music festival this summer.

The songstress is taking to the stage at London's Wireless music festival in July, and according to reports, is eager for Kate to join her entourage at the event.

The pair hit it off after being introduced at Stella McCartney's London Fashion Week party in February.

"She thinks Kate is great fun so has invited her to see her play and party afterwards," a source told British newspaper The Sun.

It was reported last week that Kate's constant gushing over Rihanna is reportedly getting on her family's nerves.

The stunning star is also said to have developed a "girl crush" on the Bajan beauty.

"When Kate first saw Rihanna at Stella's bash, she asked her ex, Jefferson Hack, to move so she could sit next to her. She spent the entire night gushing over the singer and wants to throw a party for her at her North London home," a source told British magazine Closer.

"She's confessed to her girl crush, which is driving husband Jamie Hince and daughter Lila mad."
