Beyonce JAY-Z

It has long been rumored that aging rapper JAY-Z pops pills to enhance his sexual performance. Now the 48-year-old rap mogul has been featured in an embarrassing online ad for a male sex enhancement supplement.

The erectile dysfunction advertisements quotes JAY-Z as saying “I’m amazed by the results,” and his sexual performance was “better than ever” after taking the pills. JAY-Z and his wife Beyonce recently celebrated their 10th wedding anniversary.

British actor Colin Firth, who is also featured in the ads for Biogenic XR Male Enhancement supplement, is quoted as saying, “They are the only company in the world who can effectively fight the symptoms of erectile dysfunction in a safe, natural and healthy manner.”

However, the 57-year-old ‘King’s Speech’ star tells Britain’s Daily Mirror newspaper that he has not endorsed the sex pills – and the company can expect to be hit by legal action.

“There is no connection with this product and Colin’s name is being used without authorization. Would love to introduce our lawyers to them” his spokesman said.

The company also quotes Playboy magazine founder Hugh Hefner – who died last September.

Biogenic, which is owned by two brothers, say judges on U.S. reality TV show Shark Tank invested in 25% of their firm.

The site, healthnetwork.website, claims, “After buying a staggering 25% share in the brothers company, the Shark Tank panel have personally mentored the pair, helping them undergo re-branding and re-packing of their miracle product.”
