Britney Spears has been spotted in London leaving the KISS FM radio studio wearing an engagement ring. Last week, while on her trip to the UK, Britney Spears was photographed wearing a massive rock on her engagement ring finger. Rumours of her partner Jason Trawick spotted in LA looking in Jewellers windows, sparked media gossip that the pair were set to get engaged. It was reported that Jason met with a celebrity jeweller to design a unique diamond engagement ring for Britney Spears. When the pictures emerged of Britney wearing an engagement ring last week there was much speculation as to whether the star was engaged. A source close to the star stated that the ring she was seen wearing was a ring that had previously sparked engagement rumours in the press. Another insider added Jason had not yet popped the question to Britney. In the past Britney has caused a stir by wearing a diamond ring on her wedding finger. Last Christmas she tweeted “Ho ho ho Merry Christmas Tweethearts” and then posted a picture of her wearing a diamond ring on her wedding finger. However even if reports of Britney Spears being engaged are not true, why was she spotted wearing what looked to be an engagement ring last week on her wedding finger?
