Pop star Katy Perry has sparked rumors she is set to marry her boyfriend Travis McCoy - after she was spotted wearing a diamond ring on her wedding finger.

The longterm lovers split in December after a string of arguments over the "Hot N Cold" singer's hectic tour schedule but they reconciled just months later in April.

Now it looks as if the pair could be taking its relationship to the next level after Perry was seen on an evening out in Los Angeles last week sporting a sparkler on her left hand.

The couple was previously forced to deny engagement rumors in 2008 after a New York tabloid reported that the Gym Class Heroes frontman had proposed during a trip to France over the summer.
