Justin Timberlake has reportedly rescheduled his trip to climb Mount Kilimanjaro after being forced to cancel it two years ago. The newlywed 'SexyBack' singer - who is currently on honeymoon with new wife Jessica Biel after getting married in Italy last Friday - is said to have rescheduled the challenge after being forced to pull out of it in January 2010. A source told E! News that the singer-turned-actor will join Lupe Fiasco and take part in a star-studded trek up the African peak in the near future. The source said he will follow in the footsteps of his new wife Jessica by scaling the summit in a bid to bring attention to the problem of unsafe drinking water in developing countries. The 31-year-old star previously admitted he was "bummed" after work commitments for his movie 'Social Network' forced him to cancel doing the trek alongside 'Total Recall' actress Jessica two years ago. He said at the time: "I was bummed that I wasn't able to do it, because I thought it would be a cool thing to do. Maybe one day I will. But it's really an inspiring idea and an inspiring task, and I was very proud of everyone who was involved with it. It says a lot about all the people who were involved in the climb, that they were sort of willing to put themselves out there." Justin tied the knot with Jessica last weekend following four days of celebrations at the luxurious Borgo Egnazia resort in Puglia, Southern Italy, and the couple say they couldn't have asked for a better day. Jessica, 30, sighed, "It was a total fantasy experience'', while 31-year-old Justin added, ''It was a really special evening." The newlyweds invited 100 guests to join them for their celebrations, including showbiz pals Jimmy Fallon, Andy Samberg and Timbaland.
