Here is Dallas girl Jessica Simpson in full cowgirl get-up to promote beer.

No doubt the combination of a flash of cleavage, a very sexy pout, a roll in the hay and her flowing golden locks are enough to shift a good few extra crates of the Stampede lager.

But the real revelation here is not that Jess is giving it sexy to sell stuff, but that she actually owns part of the company.

She may be blonde but she’s certainly business savvy - Jess has a 15 per cent stake in Stampede Brewers.

In the advert Jess says: “I work out and take care of myself. But I also like a cold beer once in a while.”
