Rihanna wins lawsuit against retailer Topshop

A British judge has ruled in favor of the singer Rihanna, who sued retailer Topshop for selling a T-shirt bearing her image without permission.

High Court Justice Colin Birss says buyers were likely deceived by believing she had authorized its sale.

Birss says the sales represented a loss of Rihanna's reputation in the fashion realm, where the singer has been trying to carve out a name as a designer. She has a clothing line in her name at River Island, a rival store.

The Topshop shirts were first sold as the "Rihanna Tank." After her complaints, they were sold as the "Headscarf Girl Tank" and the "Icon Tank."

The judge did not make an assessment of damages in his ruling Wednesday.

Topshop said it was "surprised and disappointed" by the judgment and would seek permission to appeal, Reuters reports.

"We robustly dispute the Judge's conclusion," it said, adding: "There was no evidence of consumer confusion to support the Judge's conclusion."

Rihanna is currently on a mini-hiatus from her ongoing "Diamonds" world tour, which kicks back up again on Sept. 13 in Macau, China.
