Jessica Simpson has come back against her critics saying that Tony Romo’s poor performance as a quarterback has nothing to do with her.

The country singer branded the rumours as ‘ridiculous’ before going on to talk about how she will support him at all his games.

She tells Extra, "I won’t be wearing the jersey to the game, but I have been there and definitely going to support the Cowboys all the way,"

Jessica added how she has written a song about the Dallas Cowboy, "He is a place of rest in my life and that's what the song is about... It's his favourite song on the record."

The track dedicated to Tony, You’re My Sunday is taken from Jessica’s new country album Do You Know.
