Choreographer and former “Celebrity Big Brother” contestant Todrick Hall may not be a homeowner after all … cause TMZ has learned, the dude’s just been hit with a lawsuit for thousands in unpaid rent.

According to docs obtained by TMZ, Hall is being sued by Avi Lavian who claims Todrick failed to pay $60k in back rent, for his Sherman Oaks home. The suit claims, Hall is supposed to pay $30k per month in rent but is now around 60 days behind.

Oddly enough, the 36-year-old singer raved about buying the lush home and gave an elaborate tour on YouTube. He said … “I have been wanting to buy a home for a very very long time, and this is a dream come true.”

Check out the video of Todrick showing off his pad and all the cool amenities … including an outdoor pool, a movie theater, an enormous walk-in closet and a bedframe decked in Louis Vuitton — just to name a few.

You might recall Todrick from the reality show, “Celebrity Big Brother.” He first gained national attention, after appearing on the 9th season of “American Idol” … he’s done quite a few gigs since then, including appearing on “RuPaul’s Drag Race” as a choreographer and judge, and working with huge stars like Beyonce and Taylor Swift.

Now, it looks like the homeowner life may not have really been a reality for the reality star.
