Jessica Simpson has fallen in love with her American football player
boyfriend Tony Romo.

The singer-turned-actress admits she can't live without the "irreplaceable"
Dallas Cowboys player.

She gushed: "I'm in love, yeah. Big time. It's only been four months. I
can't believe it. It feels like forever. I love this guy."

The 27-year-old beauty also revealed she has written a song for Tony,
entitled 'Back In My Old Boots', as a thank you for building her confidence
back up.

She told America's Glamour magazine: "Tony reintroduced me to myself. I
thought that I had to be deeper, more profound and more artsy. You change
with the guys you date. I thought I had to be more intellectual. Come on -
just be yourself!

"Tony taught me that because he loves me as me. He made me feel comfortable
again."

Meanwhile, it has been claimed Jessica has been calling Tony her "future
husband", and plans to marry him in the near future.
