Sofia Richie bobbed and weaved her way around "dumb questions" Wednesday night -- specifically whether she's a homewrecker in the breakup of Tobey Maguire's marriage -- with an assist from new coach Paris Hilton.
We got Sofia and Paris at Catch where paps grilled the 18-year-old about rumors swirling in Hollywood that she and newly single Tobey are a thing. She got testy ... fast.
Eventually, coach Paris chirped up on the subject -- telling photogs to leave her protege alone. As Paris hints ... Sofia's young and single ... and Tobey's 41.
