We guess he's moved on from muscular blondes!

Alex Rodriguez has been quietly dating Silicon Valley CEO Anne Wojcicki for over a month, Page Six reports. The baseball star's new lady love is the ex-wife of Google co-founder Sergey Brin and has way more money than A-Rod! The new couple was first spotted at a Super Bowl gathering back in February and more recently at a steakhouse in Tampa, Florida. Undercover lovers, we like it!

"Alex and Anne are spending time together and have been on a few dates. It is very new. He finds her interesting, inspirational and very smart," a source told the outlet.

Wojcicki is one smart cookie, indeed! She is a Yale graduate that started the genetic tracing company 23andMe in 2006.

The both have two kids each from a previous relationship, so it's a match made in heaven! The athlete has previously dated some of Hollywood's hottest women, including Cameron Diaz, Kate Hudson, and Madonna.

Play on playa!
