R&B singer Brian McKnight was ordered to fork over more than $340,000 to a woman who says he is the father of her 14-year-old-son.

Miriam Lee filed paternity and child support documents against the singer in Orange County, Florida last year alleging that her teenage son is the result of a brief fling she had with McKnight back in the 90’s. But since Brian didn’t file any docs addressing her claim, the judge presiding over the case ruled that he’s the daddy by default and also ordered him to pay over 14 years worth of child support, which amounts up to $341,640!

From this point forward, Brian must pay $11,388 per month but a rep for the “Back At One” singer tells TMZ:

“The judgment in Florida was a default judgment made without Brian present. He’s still looking to establish paternity, and is awaiting the results of a recent test.”

Meanwhile, Brian McKnight sang the National Anthem before the Los Angeles Angels vs. Los Angeles Dodgers baseball game at Dodger Stadium Friday (Jun 11) in Los Angeles. Check out a few pics below…
