Peter Andre recommends Viagra for Robbie Williams

London: 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.
