You would think the couple that tweets together, stays together -- but alas, it is not so.
Derek Hough and
Shannon Elizabeth posted matching Tweets last night announcing their breakup. The couple first met when they were partnered together during season six of "
Dancing with the Stars."
One of them will probably drown their sorrows at the poker table, while the other will probably spend the day at the hair salon.

Bluffs work at the tables, not in real life -- a lesson one professional poker player could learn after allegedly screwing a company out of big bucks over the movie "
Deal."
Gambling Times, Inc. claims in a lawsuit that poker player
Scott Lazar (the movie's exec. producer) promised the company a "highly visible" product placement during the film -- which starred
Burt Reynolds and
Shannon Elizabeth -- in exchange for a $50,000 investment.
But according to the lawsuit, filed in L.A. County Superior Court, the plug was far from highly visible... because it didn't exist at all.
Now here's the ironic part: G.T. is suing Lazar for no less than $1,000,000 in damages -- but the film only made... get this... $78,000 WORLDWIDE when it hit theaters back in 2008.

Shannon Elizabeth is harboring a killer! Well, not exactly. But her dog did kill a poor defenseless puppy.
Try to follow this one. Derek Hough's mom
blogged that one of Shannon's four dogs killed her daughter Katherine's maltese teacup puppy. Shannon tried to make amends by giving Derek's sis a rescue "replacement" pup.
Turns out this is a big no-no in the animal activist world -- which Shannon should know, since she founded her own dog rescue org.
Now here's the kicker. Katherine Hough has 86'd the pup and given it to her "DWTS" sis Julianne. But Julianne can't keep the dog so she's looking for a new home on her own
blog.
As they say ... screw the pooch.
Former actress Shannon Elizabeth was spotted at a gas station on Monday -- working!

Hollywood can be a dirty business.
Shannon Elizabeth doesn't think it was her fans or the judges that got her booted off -- but instead blamed her ousting on a "bigger force." And we know what it might be.
We're told the support staff at "DWTS" (think makeup and wardrobe) couldn't stand her diva ways. We're told everyone got worried when Cristian de la Fuente got injured because they figured that meant one more week of Shannon's bitchy attitude.
They were upset to see Derek finally go, but anything to get rid of Shannon.
Having a reality star for a photog is pretty cool -- except when it screws up a shot at an interview.
Check out what happened when "Dancing" hottie Shannon Elizabeth recognized TMZ's cameraman/"Big Brother 9"-reject Parker.
Priscilla Presley and the rest of the cast were asked about Elvis' ex-wife's botched injections and the secret choreographers used on the show.

The 62-year-old Scientolostar said she didn't even know what the photog was talking about -- and the rest weren't too thrilled with the line of questioning either.
While the kiddies of "American Idol" are put under lockdown, the "Dancing with the Stars" contestants were out for a tough night of "practicing" at Social. It takes brew to tango!
The "Stars" in attendance: Priscilla Presley, Penn Jillette, Cheryl Burke, Derek Hough, Shannon Elizabeth, Tom Bergeron, Kristi Yamaguchi and Jason Taylor. Eat your heart out Oscars!
She hasn't had major shine since, well, we can't remember when, but now that Shannon Elizabeth is prepping for "Dancing With The Stars", she might finally see a rise in her celebrity. Or not.
The giddy actress excitedly talked about the show and her "Dancing" partner, Derek Hough. She's finally talking about something people are interested in.

There are times when a TMZ photog comes to a celebrity crossroads, and last night found us at a difficult fork -- to follow former Laker James Worthy or comedian Richard Lewis. Too many choices!
Also in L.A: Nicolas Cage, Ben Harper and Laura Dern drove 55 to see Van Halen, Jennie Garth
got mocked after being booted from "DWTS," and Mr. Belding explained what he did with Brooke Hogan on his birthday.

While Hayden Panettiere and the hilarious cast of "The Office" brought a little A-listness to an MTV Movie Awards Luxury Lounge yesterday, the rest of the guest list read like the casting call for the next episode of "Surreal Life Does Supermarket Sweep."
Poor little Hayden was forced to surrender her hand to Jason "Gummi Bear" Davis
for a kiss, as buddy David Weintraub looked on -- with David later boasting about his big feet. Elsewhere in the suite, a busty Traci Bingham waxed poetic on Lindsay and Paris, while Bree's gay son from "Desperate Housewives," Shawn Pyfrom, showed off his Dance Dance Revolution skills.
"Road Rules" star Derrick was caught getting a manicure, "Real World: New York's" The Miz was happy to be spotted sober (for once) by TMZ, and "RW: Key West's" Johnny Bananas talked s**t about Paris until he heard she may be stopping by the suite for a visit.
"Idol" wannabeen Justin Guarini, Borat sidekick Ken Davitian and Shannon Elizabeth were also in attendance, and Shar Jackson had a tip to keep Lindsay out of trouble -- "Get an Xbox!"
