Rihanna arrived in London today ahead of her appearance on the catwalk at London Fashion Week. The Barbadian superstar, who is known for her edgy style, is launching a clothing range for River Island which will debut tonight. She expressed her excitement at the line in a video on the British Vogue website, saying: “I’ve wanted to design my own fashion line for a very long time.” “This has been something I wanted to do ever since I started loving fashion and felt passionate about it. Every time I saw something on a rack I felt like I wanted to do something different to it to change it. The only way I could do that was by designing the perfect thing for me.” She added: "The collection is causal and chic and flirty. I want girls to really want to wear the pieces and feel comfortable, but still feel edgy and I wanted the character to come out in the clothes without trying too hard. It’s just simple.” Despite reports of a rift between the 24-year-old and on-off beau Chris Brown, the singer was pictured arriving in London today wearing Chris’s leather jacket. The couple partied separately on Wednesday night, with Rihanna tweeting that Mary Jane would be her Valentine. On Valentine’s Day she posted a picture of a suspicious looking plant with the caption ‘Roses are green..’. The Stay singer then caused further speculation, when she attended a Ne-Yo concert at the Staples Centre in Los Angeles alone on Thursday night. However, yesterday Riri posted a picture of a bunch of roses along with a smiley face, hinting that the two singers might have patched up their Valentine’s squabble. For now.

Katy Perry and John Mayer looked a little bit too googly eyed during their Valentine’s Day date! Could this be because they got engaged? No it couldn’t be…they must have really just enjoyed their Vincenti Ristorante, Italian meal, in Los Angeles.

When they left the Italian, L.A restaurant, Katy was seen sporting a very, VERY, questionable ring…on her wedding ring finger.

It was also reported that Katy was wearing the same heart-shaped ring at The Grammy Awards on Sunday night.

Has the Part Of Me singer tamed the Mayer? Representatives of Katy’s have yet to respond to these allegations.

The pair have been spending a lot of time with each other lately and seem very much in love. Katy has in fact been seen wearing several different rings on her ring finger since she stopped wearing the one she wore during her marriage to Russell Brand.

In August last year, during rumours were circulated of her and John dating, Katy told said she would “never say never” to becoming a bride again. Sounds a bit like a Justin Bieber/Taylor Swift medley.

Katy added, “I guess you’d say. I’ll let love take the lead on that.”

Despite all of this, a source close to John told GossipCop the couple is still not engaged.

Perhaps a romantic dinner with someone you love is…just a romantic dinner. Do you think they couple could be engaged?
