JAMES CROMWELL: Actor James Cromwell was arrested after protesting the University of Wisconsin's alleged abuse of cats in the name of research, TMZ said.
Cromwell, 73, is known for his work on TV's "American Horror Story," "Six Feet Under" and "All in the Family," as well as in the films "Babe," "L.A. Confidential," "The Green Mile," "The Sum of All Fears," "W." and "The Artist."
TMZ said he burst into a UW system board of regents meeting Thursday, shouting and holding up a sign depicting a cat with metal implanted in its head at a UW-Madison lab.
People for the Ethical Treatment of Animals spokesman Jeremy Beckham was arrested with Cromwell, and both were charged with disorderly conduct, TMZ said.
"Today's events are just another attempt by outside activists to draw attention to a cause. They have attacked and distorted this research -- which has very real benefits for people who are deaf -- from every angle imaginable," the director of the UW-Madison Research Animal Resources Center said in a statement. "Exhaustive independent investigation by the USDA, which regulates the use of animals in research, concluded that PETA's allegations are baseless."
Also among the recording artist's famous exes are Jennifer Love Hewitt and Minka Kelly.
Mayer, 35, has been dating Katy Perry since June.
"I was just a jerk," Mayer said of his past romances in an interview to air on the next edition of "CBS Sunday Morning."

DAKOTA FANNING: Dakota Fanning and Danielle Macdonald have joined the cast of "Every Secret Thing," which Amy Berg is to begin directing in New York next month.
Likely Story, Merced Media Partners, Palmstar Media Capital and Hyde Park International announced the casting news Thursday.
Nicole Holofcener penned the screenplay, based on Laura Lippman's 2004 novel.
"The story follows two 11-year-old girls who are convicted of murdering a baby and are incarcerated until they turn 18," a synopsis said. "Upon their release, children start to go missing; as the police turn their attention to the duo, the mystery surrounding the original murder comes back to light."
Fanning and Macdonald will play the accused killers, while Lane will play the mother of one of the girls, a woman who has long known her daughter is a gifted liar. Banks will play the lead police officer, who finds herself emotionally involved in the case, the synopsis said.
REGIS PHILBIN: Television personality Regis Philbin is in talks with Fox Sports to possibly anchor a show, the New York Post reported.
Philbin, 81, left "Live with Regis & Kelly" in November 2011, reportedly after a salary dispute.
"Conversations have taken place, but any specific role, or potential show, have not resulted from those conversations or discussions at this point," a source close to Philbin's negotiations with Fox Sports told the Post in a report Thursday.
Philbin's spokeswoman told the newspaper it is "too soon" to comment on his job prospects.
