Peter Andre has offered Robbie Williams sex advice after the Take That star admitted he was injecting sex hormone.

In a recent interview, Williams said he was receiving medication twice a week because he has low levels of testosterone.

Writing in New! magazine, Andre, the former husband of glamour model Katie Price, had some different advice for the singer.

"Rob, I've got one word of advice – Viagra,” he said. “I tried it when it first came out and it was hilarious."

Williams, who is currently on tour with Take That, revealed last week that taking the sex hormone had “changed his life” and given him a “second wind”.
