LONDON: Football star David Beckham has been invited by rock star Bono to climb Mount Kilimanjaro, the highest peak in Africa.

Thesun.co.uk reports that Beckham is keen on climbing the mountain though he his busy because Bono wants him to help raise funds for the United Nations Children’s Fund (Unicef).

A source said the 19,340 feet peak is totally “outside of Becks’ normal comfort zone” but he is keen on scaling it. The source added, “He was a bit uncertain at first but he found out, like many celebrities before him, that Bono can be very persuasive. No date has been set as yet because David is very busy with his LA Galaxy commitments. There is also the insurance situation to iron out but he is absolutely set on doing it.”
