There is an investigation under way into the mysterious death of an actor who starred in multiple Lady Gaga music videos -- a 5-year-old Great Dane named Rumpus. 
Rumpus, who was featured in the videos for Poker Face, Love Game and Paparazzi, was found dead earlier this month after a hike in Los Angeles. But Rumpus' owner, Suzzane Kelleher-Duckett, tells TMZ the champion show dog had no signs of injury and appeared to be in perfect health.
An autopsy was performed a few days ago -- results are expected soon.
Rumpus was supposed to appear in Gaga's upcoming video for "Bad Romance" -- but we're told only Rumpus' mother Lava (pictured left) will now do the gig. 
R.I.P. Rumpus.

There isn't really anything that strange about that. Great Danes have a relatively short lifespan being a large dog and they often develop heart problems.

He probably died of terror upon learning he had to do yet another video with Lady Gaga.

Obviously Rumpus was partying with the wrong crowd. There had been rumors for a while that he was seen hanging out with some of Paris Hilton's pets and might have humped a dog in the Lohan camp. Probably got a hold of some bad dog biscuits and his heart couldn't take it. Chalk Rumpus up as another Hollywood casualty that couldn't handle the fame.
