London, June 7 : Singer Peter Andre has advised Robbie Williams to take some Viagra after learning that the latter has been injecting himself with testosterone twice a week.

"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!" contactmusic. com has quoted Andre as saying.

Andre doesn't rule out trying it again in the future.

"Thankfully, I haven't needed much help in that area, but I can't say I won't ever need it one day," said the singer who has two children -- Junior, 5, and three-year-old Princess Tiaamii -- with ex-wife Katie Price.(IANS)
