Peter Gallagher and Jane Kaczmarek were once married ... on NBC's 'Whitney.'

According to TV Guide, Gallagher has booked a guest gig on the new NBC comedy as Vince, Whitney's estranged father. Whitney's mother is played by 'Malcolm in the Middle' veteran Kaczmarek.

NBC said the character loves his daughter, but often has a habit of popping up at unexpected and inconvenient times.

Gallagher, who currently stars in 'Covert Affairs,' spent four years playing dad to Adam Brody on 'The OC.' His 'Whitney' episode has not been scheduled yet.

When a prostitute is connected to the death of a Navy officer, the investigators of 'NCIS' (Tue., 9PM ET on CBS) enlist Special Agent Tony DiNozzo (Michael Weatherly) to go under cover as one of her clients.

"Guess you're not room service, huh?" he says awkwardly, just before she slaps him. (Gulp.) "It's fun to watch," says Holly Snow (Dina Meyer) from a nearby room, recruited by the NCIS gang to relay the perfect call-girl code words into DiNozzo's earpiece.

By the end of the set-up, somebody needs a cold shower.

(S02E15) "Tell Mr. Jane he is a mean, irresponsible sadist." - Abigail to Lisbon

Dina Meyer is everywhere on TV lately, isn't she? If you are like me, as soon as you see her appear in one of your favorite TV shows, you know there's an extremely good chance that she ends up being the culprit or that she'll at least have a meaty role.

Her 'The Mentalist' guest appearance was no different, and she ended up being either the culprit or with a meaty role. Was she the killer of the week or a red herring? The answer after the jump. One thing is certain, her role had character, as she had to say that Jane was mean, irresponsible and a sadist!
