Bachelor and bachelorette parties have a reputation for being nothing but trouble.

  • Nicole Richie

    Rumor has it that it wasn't just Nicole Richie who got wild at her bachelorette party in 2010. Pal Christina Aguilera had a little too much fun and, according to <a href="http://www.radaronline.com/exclusives/2011/03/exclusive-christina-aguilera-raunchy-pix-sale-bed-with-boyfriend-nicole-richies" target="_hplink">RadarOnline,</a> reportedly left behind a memory card full of photos in a French hotel.

Other photos on the card included Aguilera in bed with current beau, Matt Rutler.

Perry, now divorced from Russell Brand, also eyed strippers who were dancing to her songs.

  • Brad Pitt

    Brad Pitt's bachelor party was fit for a king. According to the <a href="http://www.dailystar.co.uk/goss/view/252874/Brad-Pitt-s-party-mad/" target="_hplink"><em>Daily Star</em></a>, Pitt and high-profile friends such as Harvey Weinstien and Ray Liotta partied hard in Cannes, France, following the premier of Pitt's new film, "Killing Me Softly." Rapper P. Diddy toasted Pitt and invited the entire party to continue the night on his yacht.

  • Blake Shelton

    Country singer and "The Voice" judge Blake Shelton didn't want a true bachelor party, <a href="http://www.parade.com/celebrity/celebrity-parade/2011/03/blake-shelton.html" target="_hplink">reports <em>Parade</em>.</a> Shelton told the magazine that he and some friends were going camping to "find something to hunt." He said that most of his life has been a "bachelor party" so he didn't feel he needed another wild night (though some might say that hunting on your so-called last night as a single man is a pretty "wild" thing to do).

  • Tony Romo

    NFL star Tony Romo did just the opposite of what most men do at bachelor parties. <a href="http://www.usmagazine.com/celebrity-news/news/tony-romo-i-didnt-drink-at-my-bachelor-party-2011168" target="_hplink"><em>Us Weekly</em> reported in 2011</a> that Romo said he didn't feel like drinking the night of his party but that he also didn't want that to impact the fun. He told the magazine, "So I was like, let's find something to do here. We tried coming up with a game, and with 14 or 15 guys, there ain't a lot of non-drinking games at that age that you can do." Romo and his buddies opted for a game of nighttime hide-and-seek instead.

  • Chris Bosh

    Miami Heat star Chris Bosh's bachelor shindig lasted for four days in Las Vegas, and was nicknamed "Hangover 3," <a href="http://www.nypost.com/p/pagesix/bosh_four_day_bachelor_bash_sQSV125vkVP3lXfqnoNTaM" target="_hplink">reports the <em>New York Post</em>.</a> Bosh and friends saw Chris Angel's magic show, and Bosh was even invited on stage to participate. The next day, they paint-balled and partied, and then finished the weekend with a comedy show and boys' casino night at Caesar's Palace.

  • Wes Welker

    The New England Patriots' wide receiver Wes Welker had a major party foul at his recent "unofficial" bachelor party. <a href="http://www.nfl.com/news/story/09000d5d829f2bf3/article/wes-welker-reportedly-in-scuffle-at-bachelor-party?module=HP11_headline_stack" target="_hplink">NFL.com reports</a> that Welker and his buddies tried to crash a "Summerology" party by Patron at Above the Salt restaurant while celebrating in Aspen, Colo. in June 2012.
