You'd think that a Russian billionaire could do pretty much whatever he wants regardless of the current state of economy, right? Not so much, says Roman Abramovich, who has postponed his wedding to Dasha Zhukova—patron of arts and soul of discretion—because of the financial crisis. The 41-year-old Russian mogul, who came in at No. 15 on Forbes' list of the world's richest earlier this year, was due to tie the knot with 26-year-old Dasha this month. Now he's reportedly told her that, "Now is not the time to party." Not that we would ever suggest that Roman's decision was based on anything other than a well-developed sense of restraint and a need to keep a close eye on his global business interests, but he's provided a handy excuse for much poorer commitment-phobes!
