Talk about a big-name merger.

Boston Red Sox third baseman Kevin Youkilis is engaged to marry one of the sisters of New England Patriots quarterback Tom Brady, according to a Red Sox team source.

Youkilis first met Julie Brady, who is one of three Brady sisters, at a Patriots party after the team was knocked out of the 2010 playoffs, according to the Boston Herald, which first reported the story.

She is a schoolteacher with a 5-year-old daughter and has never been married, according to the newspaper. In 2008, Youkilis had a marriage ceremony with Enza Sambataro, who had dated Ben Affleck, but the pair reportedly never filed the necessary paperwork to make the union legal. They split up two years later.

Sources tell the Herald that Youkilis was at Lucas Oil Stadium in Indianapolis to watch the Patriots in Super Bowl XLVI.

"He's really lucky," an unnamed friend of Youkilis told the Herald. "She's a really nice person, but all the Bradys are nice people."
