The 39-year-old actor sent the rumour mill into overdrive when he was spotted wearing a silver band on his wedding ring finger in a photo he posted on Twitter.
The actor has put an end to the speculation in an interview to E! Online.
When asked if he was engaged, or indeed married, he said, "I'm just wearing a ring, man. It's the only finger this ring fits on. I like to keep them (fans) guessing. I don't know, we'll see what happens."
