Chris Brown is reportedly getting close to Topshop heiress Chloe Green.

The rapper has been spending more time with the shoe designer - despite his ex-girlfriend apparently Rihanna suing her father Philip Green's British high street store for selling t-shirts using her image without permission.

Chloe - who recently split from Marc Anthony - has been spotted with Chris, 24, more frequently since his relationship with the "Stay" singer came to an end - something an insider claims Rihanna will "definitely" know about.

"Chloe met Chris last year when he serenaded her at her dad's 60th birthday party. She was always a big fan and thinks he's really hot. After he split with Rihanna and she split from Marc, they've been spending more time together and having a lot of fun. It's early days, but they've not been shy about being seen out at the same places ... It's the sort of thing Rihanna keeps an eye on, and she's definitely aware of Chloe being on the scene," a source said.
