American football star sings Journey's Don't Stop Believing

Jessica Simpson received an early birthday present from boyfriend Tony Romo when he gave her an impromptu song.

The pair were partying at Key Club in West Hollywood when the American football star grabbed a karaoke mic and started singing rock band Journey‘s Don’t Stop Believing.

‘He sings that one all the time,’ manager Mark Buccola tells People.

And it’s not the only treat Tony, 28, has given Jess in preparation for her big day.

He also took her on a beach holiday to Destin Beach in Florida for the weekend.

Jessica turns 28 tomorrow.
