LEGAL MATTERS

It seems even Lady Gaga, 24, has her limits. Lawyers for the pop star are threatening to sue London shop the Icecreamists for trademark infringement if they don't change the name of their $22.50-a-serving vanilla-and-lemon-infused Baby Gaga ice cream made from human breast milk. The shop owner said he is prepared to fight. •Model Theodora Richards (inset), 26, the daughter of Rolling Stones rocker Keith Richards, 67, was arrested in Manhattan on March 1 for allegedly possessing a controlled substance and for writing graffiti on the side of St. Anthony's Convent. Richards reportedly wrote "T [heart] A" with a red marker. She did not enter a plea and was released without bail.

DIVORCING

Tarnished baseball great Pete Rose filed divorce papers in Los Angeles on Feb. 25 to end his 26-year marriage to wife Carol, 56. The all-time hits leader, 69, who in 1989 was banned from the game for life, asked that he retain miscellaneous jewelry and all his memorabilia from before their marriage.

WED

Talk about working undercover. Austin Powers star Mike Myers, 47, and his girlfriend Kelly Tisdale, 34, announced that they quietly married five months ago in what his rep called "a private ceremony...celebrated with family and friends." This is Myers' second marriage, having split from actress Robin Ruzan in 2005. The couple had no children together.

BABY ON BOARD

It's double the joy for Fried Green Tomatoes star Mary Stuart Masterson, 44, and her husband, Army Wives actor Jeremy Davidson, 39. Davidson said that the couple are "in happy shock" about expecting twins, who will join their son, 1. Guy Ritchie, 42, and his girlfriend, model Jacqui Ainsley, 29, are expecting their first child together. The British director is the father of Rocco, 10, and David, 5, with ex-wife Madonna.

AILING

Actress Zsa Zsa Gabor, 94, was rushed to a Los Angeles hospital on March 2 after a clot formed in her left leg and cut off the flow of blood. She returned home a few days later after refusing surgery to remove it because "she doesn't want to suffer anymore," says her husband, Prince Frederic von Anhalt, 67. Doctors amputated most of her gangrenous right leg in January.

PAYBACK

Some of music's biggest stars have entertained Libyan dictator Muammar Gaddafi, 68 (inset). Now that the leader is violently suppressing the uprising sweeping his nation, many are racing to return concert fees. Mariah Carey, 41, who feels "horrible and embarrassed," intends on giving away profits from her song "Save the Day." Usher, 32, who performed for Gaddafi's son Mutassim in 2009, is "sincerely troubled" that he sang, and plans to donate his fee to human rights groups. Beyonce, 29 (left), who sang at that same concert, had last year already given $1 million to the Clinton Bush Haiti Fund.
