The news that Peter Krause and Lauren Graham, co-stars of the NBC dramedy 'Parenthood,' are a real-life couple may have icked some of you out, but I didn't bat an eye.

First of all, who cares what celebrities do when the cameras aren't rolling? Secondly, it's happened so many times before that the CDC needs to classify it as some sort of medical epidemic.

It makes sense, in a way. TV actors spend 11 hours out of their 12-hour work days waiting to shoot scenes and a few relationships are bound to bloom. And to prove it, here's a list of nine TV couples whose relationships started on a simple sound stage in between endless takes and blossomed into a lifetime of endless love (right up until the divorce settlement).

'Parenthood' stars Peter Krause and Lauren Graham have officially come out as a couple. According to People, the actress confirmed the rumors to Redbook magazine. The couple play siblings Adam and Sarah Braverman.

"Nobody knew about it for awhile, because we like to be at home, cooking and not going out," Graham told Redbook in its upcoming Sept. 21 issue. "I've also been really protective of it, because it's important that you can buy us as brother and sister on the show."

This makes Krause and Graham the latest in a line of faux incestuous TV couples -- actors who play relatives on-screen while engaging in a romantic relationship off-screen. Married 'Dexter' stars Michael C. Hall (Krause's 'Six Feet Under' castmate) and Jennifer Carpenter portray (adoptive) siblings Dexter and Debra Morgan.

Anna Paquin and Stephen Moyer, the stars of HBO's vampire drama 'True Blood,' were married Saturday night in a wedding at a private, oceanside Malibu residence.

According to UsMagazine.com, guests at the ceremony uniting Paquin, 28, and Moyer, 40, included 'True Blood' costar Carrie Preston (attending with husband Michael Emerson of 'Lost') as well as Elijah Wood, Paquin's costar in the upcoming film 'The Romantics.' Many friends and loved ones who attended the nuptials reportedly arrived bearing gifts entirely wrapped in purple.

The couple -- whose first kiss was onscreen, playing psychic Sookie Stackhouse and vampire Bill Compton on the HBO hit -- officially went public with their romance in February 2009. "I love working with her," Moyer told E! last summer, "and that's how it all started, by falling in love on camera."

Here we go again. This week's public outing features Michelle Rodriguez - star of Girlfight, former Lost cast member and ex-jailbird. I know. I know. You didn't realize that she wasn't out.

In an interview with The Advocate, The L Word's Kristanna Loken implies that she is in the middle of a hot and heavy romance with the late Ana Lucia. The Advocate questioned Loken directly about the relationship, and while she coyly eluded their inquiries, The Advocate went ahead with a "Michelle & Kristanna in love!" headline.
