Rihanna is known to be a big fan of Topshop ... or was, anyway.
She is often seen browsing their clothing at the Oxford Street store or palling around with Topshop heiress Chloe Green ... but she's not happy with them now.
She's suing the British retailer for $5 million. Over this:
According to a "source," Rihanna has been feuding with Topshop and its parent company, Arcadia Group, over the shirt that uses her likeness.
Topshop claims to have purchased the Rihanna photos in question from the photographer, but "do not pay the artist licensing fees." She begs to differ.
So far, neither Rihanna nor Topshop have mentioned of the dispute on their Twitter accounts, so it appears she is at least trying to keep it private.
That would be a first for Chris Brown's ex.
