Kayte Walsh will never leave husband Kelsey Grammer's side ... literally. The former flight attendant and fourth wife of the Boss star is now a permanent part of the actor's life, as well as his body. That's because the 57-year-old actor got his new spouse's name tattooed on him. They are now joined at the hip, which is exactly where her moniker sits. The serial groom spent the weekend in a Chicago tattoo parlor getting inked. A source tells Radaronline.com, "Kelsey was so enamored with his wife -- it was all about her. It was obvious that he really cares a lot about her. He loves her so much he wanted to do something special. Kelsey was awesome and didn't seem too bothered by the pain. He was also super polite and friendly to everyone in the shop." For Grammer's sake, we hope his marriage to Walsh lasts as long as his new body art. Or that he has the number for a tattoo removal place in his rolodex.
