Spencer Pratt thought about making a sex tape with his wife Heidi - but decided against it because he wouldn't make enough money.

The 33-year-old reality star admits he and his spouse have thought about ways to boost their fame, and he seriously considered going down an x-rated path, but the blonde beauty wasn't so keen.

He said: "I talked to the guy who did Kim Kardashian's sex tape [with Ray J].

"[But] there's no up-front money. And the negativity? It's tiresome.

"But, more importantly, Heidi was like, 'Over my dead body.' "

But the couple - who met on 2010 reality show 'The Hills' - think having a baby could land them a show of their own, even if they aren't as entertaining as fellow stars Rob Kardashian and Blac Chyna, whose explosive relationship has been chronicled in E! show 'Rob & Chyna'.

Spencer told heat magazine: "I don't believe our lives are entertaining enough to hold down a show... Maybe if Heidi was pregnant, I don't know there's more fighting all the time with Rob and Chyna.

"Heidi and I don't fight. People want drama, they don't want lovey-dovey."

And the pair don't really have a cast of pals that could appear on any future reality show as Spencer admits his 30-year-old wife is his only friend.

He said: "I live more of a virtual existence. I don't really have any friends.

"All my contacts have disappeared now that my millions aren't flowing in any more."
