TMZ just caught up with Shaniqua Tompkins as she got back to her house — or what’s left of it after this morning’s big blaze — and 50 Cent’s ex-shawty went OFF! 

Where do we begin? She alleges that he tried to kill her, that he’s obsessed with her, and — well, just listen to this crazazy rant!

We put in a call to Fiddy’s lawyers, and they haven’t gotten back to us.

The lawyer for 50 Cent’s baby mama, Shaniqua Tompkins, tells TMZ that she heard “someone” come into the house this morning at 4 AM, shortly before the fire broke out around an hour later.

Paul Catsandonis, Shaniqua’s lawyer, tells us that his client is “traumatized” by the fire and that the kids are similarly in total shock. Six people, including Tompkins and their 10-year-old son Marquise, were in the house. They all were transported to the hospital and treated for smoke inhalation.
