Redfoo and former Boyzone star Ronan Keating dressed up for a three-hour charity motorcycle ride on Sunday (28Sep14).

The stars, who are both judges on The X Factor Australia, rode classic motorbikes on a route beginning at Sydney University as part of the annual Distinguished Gentleman's Ride, a global one-day fundraising event.

The ride, which took place in more than 220 cities worldwide on Sunday, raises money and awareness for prostate cancer charities and the male participants have to wear their finest formal attire during the trek.

The LMFAO star wore a glittery, leopard print suit jacket and trademark white glasses while Keating wore a classic waistcoat and bow tie.
