(CNN) -- The National Football League said Saturday that it is reviewing reports involving Minnesota Vikings quarterback Brett Favre after a sports website posted naked pictures, text and voice messages it alleges he sent to a model and former television host.
When asked about the allegations Friday, the star quarterback declined to comment.
Greg Aiello, an NFL spokesman, said the league is reviewing the matter, but declined further comment.
CNN could not independently confirm whether the voice heard in the recordings belonged to Favre, or whether the notes were in fact sent by him.
The website Deadspin reported the messages were sent while Favre played for the New York Jets. The recipient, Jenn Sterger, worked for the team at the time as a sideline personality and host, Deadspin reported.
"Love to have you come over tonight," a man can be heard saying in one of the voice messages posted by Deadspin.
The website also alleges Favre left messages on Sterger's MySpace page and sent her pictures of himself, naked from the waist down.
A spokesman for Sterger declined to comment on the reports Friday.
Favre signed with the Vikings in August 2009 after coming out of retirement for the second time in as many years. He played for the Jets in 2008, after playing for most of his career with the Green Bay Packers.
Favre has been married for 14 years.
