Ashton Kutcher threw some water on it at a Kenny Chesney concert in Anaheim, Calif., over the weekend.

The "Two and a Half Men" star donned a full cowboy look for the Saturday show, wearing a plaid button-down shirt and cowboy hat -- and also took the time to fling some water at the X17Online photographers snapping away at the concert. Whether it was in jest or out of annoyance, we can't say for sure, but the act places Kutcher among Justin Bieber, Alec Baldwin and other celebrities who've scuffled with the paparazzi in the past.

Kutcher, 34, is rumored to be dating former "That '70s Show" co-star Mila Kunis, 28; the pair were recently photographed whizzing around Los Angeles on a motorcycle and sharing an intimate poolside embrace on the July 4 holiday.

  • Alec Baldwin

    On June 19, actor <a href="http://www.huffingtonpost.com/2012/06/19/alec-baldwin-denies-punching-nydn-photographer-say-rep_n_1608846.html" target="_hplink">Alec Baldwin allegedly punched <em>New York Daily News </em>photographer Marcus Santos</a>, as he was leaving the city Marriage License Bureau with his fiancee, Hilaria Thomas. Santos claims the photographers stepped back to give the actor space, but he lunged at them, first grabbing another paparazzo, before Santos says he interrupted. "Don't touch him.' I knew he was going to attack me. I stepped back, and he kept coming," Santos told the paper. "He comes after me, starts shoving and punching me -- one time, right in the chin. And then he started shoving me, and pushing me. Then he goes the other way." Santos later filed an assault complaint with New York Police Department and the incident is being investigated. The actor's rep released a statement denying that Baldwin ever threw a punch: "As Alec and his fiancee were leaving City Hall, a 'civilian' walking in front of Alec positioned himself to obstruct the view of a photographer aggressively trying to shoot the couple. The photographer was clearly frustrated, pushed past the bystander and assaulted Alec with his camera. There were no punches thrown, and any subsequent physical contact was simply Alec protecting himself."
