According to In Touch Weekly, Vergara and Manganiello are desperate to have a family together while the actress has been thinking about having a second child for some time now. Vergara, 42, already has one son, Manolo, 22, from a previous relationship.

A source told the site, "Sofia and Joe will use a surrogate, but the baby will be their biological child, conceived with Sofia's egg and Joe's sperm."

Apparently, the couple has been looking for potential surrogates for some time now as they are working full speed ahead on their plans.

Meanwhile, there has been a new rumor suggesting that Manganiello might guest star on Modern Family.

OK! Magazine reported on Wednesday that the Hollywood actress is campaigning to have Manganiello on the show. Vergara plays Gloria on the highly-acclaimed sitcom and so far has been nominated for four Emmy Awards along with several more accolades.

A source tells the site, "Sofia thinks Joe would be a perfect guest star on Modern Family - and the sitcom's writers agree. Casting Joe would bring headlines - and ratings."
