The Olympic gold medallist, who is rumoured to have developed a close friendship with Cher after splitting from his wife of 22 years, Kris Jenner, in October, reportedly isn't enjoying the couple's lavish three-day nuptials.
A source told gossip website RadarOnline.com: ''Bruce is having a terrible time and he is bored out of his mind.
''Once again he feels like a prop in the festivities. Kris has been barking orders at everyone since they arrived in Paris for Kim's wedding. He just wishes he could have stayed at home and played with helicopters.''
The estranged spouses were both spotted wearing their wedding rings during Kim and Kanye's pre-wedding celebration at the Palace of Versailles on Friday night (23.05.14), but the insider insisted: ''Kris is only wearing her wedding ring in hopes the media will speculate that she is getting back together with Bruce.''
Bruce, 64, plans to be ''on the first plane'' back to his bachelor pad in Malibu, California after walking his stepdaughter, 33, down the aisle at the Forte di Belvedere in Florence, Italy today (24.05.14) and attending the couple's post-wedding brunch on Sunday (25.05.14).
The source said: ''He has no plans to stick around any longer than needed.''
