The rapper, whose real name is Curtis Jackson, arrived in court Tuesday for the start of the trial of his lawsuit against BVH Integrated Services.
He hired the company when he bought his Farmington mansion in 2003 and repairs were to cost $44,000, but the lawsuit says the company billed him for $2.7 million.
The lawsuit was first filed back in 2006.
BVH calls the claims "fabricated" and says it received no complaints from Jackson until the lawsuit was filed.
The case is being heard by a Hartford Superior Court judge.
