Yes, celebrities have been behaving a lot like children lately-and Ed Board is getting tired of it.

Let’s start with the clash of the “titans:” Donald Trump versus Rosie O’Donnell. In late December, Rosie slammed Donald for allowing Miss USA, Tara Conner, to keep her crown despite allegations of underage drinking, drug use and inappropriate sexual behavior.

Rosie openly imitated and mocked Trump (and his hair), poked fun at his list of failed marriages, and then went on to criticize Trump’s financial standing-which of course, The Donald wouldn’t stand for. Trump announced that he was going to sue “fat little Rosie” and called her a “slob” and a “loser.” And the two have more or less continued in that immature vein ever since.

Ed Board thinks someone should inform these two that they are two of the least popular “celebrities,” and their feuding doesn’t really help matters. Their unflattering insult exchange has reflected poorly on both of them, and neither of them intends to stop fighting anytime soon.

There is another issue that has swept headlines: the tension on the “Grey’s Anatomy” set regarding Isaiah Washington and T.R. Knight. Last October, Washington and fellow “Grey’s” cast member Patrick Dempsey were involved in an argument that resulted in Washington using an anti-gay slur against co-star Knight. Knight later officially came out as gay.

This seemed like the end of it until the Golden Globes in January when Washington, after being asked by reporters if he referred to Knight with an anti-gay slur, said that he did not call Knight a “faggot.”

The backlash from this is ridiculous. They asked him a question and he answered it. It probably would have been a better idea to say, “No, I did not use any homophobic language.” But the press shouldn’t have been asking those kinds of questions at a completely unrelated event that was held three months after the original altercation!

It has been revealed that Washington did use such language toward Knight and is now in rehab, leaving ABC executives and “Grey’s Anatomy” producers in the lurch. You would think that being stars on the No. 1 show on television would leave you wanting to move on with your job, especially after managing to do so for three months before the Golden Globes incident… but you’d be wrong.

Celebrity feuding is nothing new. Hilary Duff versus Lindsay Lohan. Michael Jackson versus Paul McCartney. Jay Leno versus David Letterman. The tabloid-obsessed American public has even invented feuds where there is nothing to suggest an all-out public feud. (We’ve still got our Team Aniston shirts to prove it.)

Ed Board would like to think that if we weren’t so obsessed with the lives of celebrities, the unnecessary fussing and fighting would cease. We would really like to think that. But Rosie and Donald’s case proves that even the most uninteresting and unlikable celebrities have feuds.

So here’s Ed Board’s message to feuding celebrities: Grow up!
