Willie Nelson thinks you should know a thing or two about some cows. The country crooner is joining in on a campaign along with the Animal Legal Defense Fund to raise awareness about cruel-and illegal-living conditions for calves raised to produce milk for dairy products. Moo! Boo!

Specifically, they are targeting Land O'Lakes and Challenge Dairy to get them to stop using milk from calves that come from California's Mendes Calf Ranch - which employs an intensive confinement practice (keeping calves in cramped, filthy crates - sometimes without room to turn around or lie down) and is the subject of a lawsuit brought by the ALDF.

Nelson has written a letter to the companies and is urging others to join the petition, www.FreeBabyMendes.com, that is already 22,000 people strong.

TMZ.com contacted Mendes Calf Ranch who had no comment on the issue.

Aretha should know, fur is definitely out of fashion. Hasn't she seen all those shots of Paris and Britney getting out of cars?

Scarlett Johansson's muscled borefriend Ryan Reynolds landed in Boston on Monday -- with his pooch in an emasculation chic pouch.

No word on where he packed his balls.

Where would helpless pups be without Gavin DeGraw? The musician was in L.A. last week when a TMZ spy spotted him saving a stray dog.

After seeing the deserted pup was hurting, Gavin and his brother Joey went into 911 mode. According to Gavin's dad, Gavin and Joey took the stray to the vet and paid for all the Rx. And then they found doggie a new home.

All of Jacko's pets, including giraffes, giant pythons, parrots and a menagerie of other species, were purchased by Banjoko Nature Preserve in Arizona. The creatures are intended to be "presented center-stage at a 185 acre planned multi-million dollar wildlife preserve."

Unfortunately, the animal was so frightened it ran away from the modern-day hero and down a freeway ramp. Why would the poor canine be so frightened by P!nk? She's so, er, soft and tender.

Yes- this is the guy that allegedly sleeps with her.

Sandy and hubby Jesse James were seen leaving their home with bi-pedal dog Ruby and three-legged pooch Poppy. Both dogs were rescued from shelters a few years back.

While no racial tirades were reported, Rourke showed off his new "Bounty Hunter" mullet-chic mug on the Jersey set of his new film on Thursday. It's amazing what Mickey can do to his looks -- and without the use of CGI.

Who do they think they are, Brangelina?!? Hopefully they picked up this dog's poop!

Carter was popped in Texas yesterday on charges of possession of at least two ounces of pot. But he had two pit bulls with him at the time -- one puppy and one full-grown.

When AC was taken to jail, his dogs went to the pound. As soon as he was sprung, he went to Sam B. Coffey Animal Shelter to retrieve them -- and had to pay a $70 impound fee.

The woman who runs the shelter tells TMZ that Carter's dogs "were very, very well-trained" and that Aaron was "extremely happy to see his dogs and they were well cared-for."

This has to stop.

We kid, of course, but consider the evidence: First, he dresses the cute critter in a two-tone green sweater, all matchy-matchy with his even greener pants. Then, he prances the pooch for blocks in a busy part of the West Village.

She gets no love from them either.

Rowe ge$tated Jackson's first two children, Prince Michael and Paris.
