Peter Andre had a "hilarious" experience after taking Viagra.

The 'Behind Closed Doors' hitmaker - who has children Junior, five, and three-year-old Princess Tiaamii with ex-wife Katie Price -tried the drug, which is used to treat impotency, when it first came on the market and thinks Robbie Williams should also attempt it after the Take That singer recently revealed he has injections of Testosterone twice a week.

Peter said: "Rob, I've got one word of advice for you, Viagra.

"Go and get it and have fun! I tried it when it first came out to see what all the fuss was about. I'll spare you the details, but it was hilarious. Talk about an extra boost!"

Though Peter - who has been single since splitting from model Elen Rivas in April - insists taking the drug was a one-off, he hasn't ruled out trying it again in the future.

He added to new! magazine: "Thankfully, I haven't needed much help in that area, but I can't say I won't ever need it one day!"
