Allison Mathis is demanding child support from Raptors forward Chris Bosh, saying he paid for fertility drugs, then left her when she was pregnant.

The lawsuit claims Bosh broke up with Mathis when she was seven months pregnant, leaving her without medical care even as she fell ill.

Mathis, who is seeking child support and sole custody, alleges that in 2008 the former couple planned to get married.

According to the lawsuit, they made a consensual decision to have a child together and Bosh paid for a fertility drug to hasten the process.

Bosh is denying the claims.
