Jessica Simpson's boyfriend Tony Romo has laughed off reports the pop star's dad has driven a wedge between the two lovers, dismissing the rumors as "laughable".

The couple was alleged to have split last month, with American tabloids claiming Romo ended the relationship after growing sick of Joe Simpson meddling with their romance.

Simpson and Romo have since been photographed out and about together, putting on a united front against the accusations.

Joe - who manages both Jessica and Ashlee Simpson - recently hit out at the allegations himself, insisting he hasn't stepped over the line.

And now Romo has issued a brief statement to People.com in a bid to silence their critics.

He says, "It's all laughable. (Joe's characterization is) so far from the truth."
