Jessica Simpson is denying rumours that she and quarterback boyfriend Tony Romo have been shopping for a wedding ring.

The country singer - who has been dating Tony since late 2007 - says that she finds the rumours hilarious and insists that her beau's spending habits are not so lavish.

She says, "It's funny to me that people are saying that Tony and me are out shopping for diamonds.

"Trust me, we're not out shopping for diamonds - if anything we are out going to buy DVDs.

"That's pretty much it. We have movie nights and cooking and ordering in, but there has not been any diamonds in this relationship."

Maybe Jess has been spending her boyfriend's hard earned cash on something a bit more eye-catching...
