London, Sep 7 - American pop singer Katy Perry has sparked rumours that she is set to marry her boyfriend Travis Mccoy after she was spotted wearing a diamond ring on her wedding finger.

The long-term lovers split in December last year but they reconciled this April.

Now it looks as if the pair could be taking the 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, reported contactmusic.com.
