Kelsey Grammer's children from his third marriage to Camille Grammer, daughter, Mason, 10, and son, Jude, 7, are perplexed about his decision to tattoo his fourth wife, Kayte's name on his hip, because he has forbid them from ever getting inked, even when they become adults, RadarOnline.com is exclusively reporting.

As RadarOnline.com previously reported, the 57-year-old sitcom star got Kayte's name tattooed in Chicago on Saturday. Kelsey's much younger pregnant wife was with him when he got his first tattoo.

Maybe he’s in it for the long haul this time!

Kelsey Grammer got his first tattoo this weekend and inked his fourth wife’s name, Kayte Walsh, onto his hip.

There's been no lack of bad blood as Kelsey and Camille Grammer called it quits to their 14-year marriage, but the Real Housewives of Beverly Hills beauty insists she's not changing her last name because of the bitter break-up.

"Our children are Grammers and it's easier to keep the Grammer last name because of them," Camille told Wendy Williams on Thursday. "There's so much paperwork that goes with changing a name. We're still going through [a custody battle] ... it's just easier."

Camille explains why she thinks Kelsey was eager to see her land a spot on Bravo's reality franchise: a cover for his affair with now-wife, and former Virgin Atlantic flight attendant, Kayte Walsh.

Kelsey Grammer made an embarrassing slip up to Jimmy Kimmel that revealed the depth of his adulterous ways, and RadarOnline.com has video of his accidental confession.

The former Frasier star described his first encounter with his fourth wife Kayte Walsh as a "magical night," when he appeared on Jimmy Kimmel Live on Wednesday, but the memorable occasion in December 2009 was six months before he split from wife number three, Camille Grammer.

"We actually met in the air on a plane to England," a gushing Grammer told Kimmel.

Kelsey Grammer took yet another jab at ex-wife Camille on Piers Morgan Tonight, saying he thought she "married me because I was Frasier."

The Emmy-winning star of TV shows such as Cheers and Frazier told Morgan that the stint on Bravo's The Real Housewives of Beverly Hills was his "parting gift" to his ex, who he's currently in a nasty custody battle with after their divorce following 14 years of marriage.

Grammer said of the Real Housewives: "Whether or not it worked well for her doesn't matter -- it was my way of saying, 'Look, you always wanted to be famous. Here you go.' "

Kelsey Grammer reportedly melted down after the taping of Sunrise, an Australian TV morning show, when the program’s entertainment producer played clips of he and ex-wife Camille in better times throughout his live interview on Tuesday.

"You are a vile person ... a sick dog ... your life must be tragic ... I feel sorry for you," The Frasier star was heard screaming, according to the Herald Sun, adding he sprinkled in many profanities during the tirade.

Grammer would not be invited back onto the show, an insider told the paper.

Kelsey Grammer says he and his new wife Kayte Walsh "have plans" to have children in the near future.

"We're working on it," the Emmy-winning star of TV shows such as Cheers and Frazier told our friends at Hollyscoop.com. "So we'll see when it happens.”

The 56-year-old actor is currently embroiled in a nasty custody battle over his two sons with his ex-wife Camille, in the wake of end of their 14-year marriage earlier this year.

He told Hollyscoop.com he's going to see the boys "as often as I can.

Kelsey Grammer brought his new bride, Kayte Walsh, to a custody showdown with his ex-wife, Camille Grammer, RadarOnline.com is exclusively reporting. Camille Grammer is at the courthouse, with her powerhouse lawyer, Neil Hersch.

Walsh wasn't allowed in the courtroom, and had to wait out in the hallway. Cases involving children are closed to the public, and interested parties are only allowed to attend.

During a break in the proceedings, Kelsey emerged from the courtroom, and gave his fourth wife a big kiss on the lips. An eyewitness told RadarOnline.com: "It was rather inappropriate."
