Jefferson Airplane

front woman and Rock and Roll Hall of Famer

Grace Slick

is also a painter - fact, some call her a "painter-extraordinaire." (That'd be the PR folk who wrote the news release.)

The 66-year-old psychedelic goddess, who studied art as a youth at the University of Miami, decided in '89 to pick up the brushes once again and let loose on stretched canvas. You can see her work - and her - at a two-day show at Wentworth Gallery at the Court in the King of Prussia Mall Saturday from 6 to 9 p.m. and Sunday from noon to 3 p.m. Info: 610-337-8988 or www.wentworthgallery.com.

From 'L&O' to the Oval?

Former U.S. Sen.

Fred Thompson

, who plays the delightfully gruff district attorney Arthur Branch on NBC's

, is exiting the show - possibly to run as a Republican candidate for president.

Thompson, who represented Tennessee, has yet to make an official announcement but has been making exploratory appearances and blogging on issues.

NBC entertainment prez Kevin Reilly said Thompson will leave even if he decides against running.

Bruce Willis

finally asks what's been on every citizen's mind for years: "Why do actors think their opinions mean more because [they] act?" Bruce says he's sick of celebs who act like self-appointed experts on everything around the globe.

John McClane

can no longer say his most excellent

Die Hard

catchphrase, "Yippe-ki-yay, [filthy word]."

Talented, sexy, lippy and filthy rich

Mick Jagger

: "Hopefully that big love will happen again with someone else, but I'm quite resigned that if it doesn't, I will still find ways to be happy."

Baby roundup

Sheryl Crow

spent Mother's Day with her own child,

Donald Trump

is a grandpa. On Saturday, The Donald's son,

Donald Trump Jr.

, and wife

Vanessa

welcomed their first babe, the 6-pound, 14-ounce girl,

Kai Madison

. (Wonder how many times gramps'll do the "you're fired!" thing at Kai till she can finally leave home for college . . . in

18 years

?)

Mary J. sizes up her man

about her courtship with her love, hubby

Kendu Isaacs

. In an interview with Essence mag, Mary says Isaacs "had this 'I can take care of you. I can make you feel safe' thing. And I needed that."
