Tobey Maguire and wife expecting their second child

Tobey Maguire and his wife, Jennifer Meyer, are expecting their second child together later this year, it has been revealed.

The couple -- who are hoping for a boy -- will become parents for the second time in October.

A source said: "Jen and Tobey are over-the-moon happy.

"Since they already have a daughter, they would love a little boy, but of course they would be just as thrilled with another daughter."

The source adds that the pair -- who married in September last year -- always planned to have another child within two years of the birth of their daughter, Ruby, who is 17 months old.

"Jen's doing great," the insider tells In Touch Weekly. "She had an easy pregnancy last time around, so this time it should also be a breeze."

Jen and Tobey are currently building a new multi-million dollar home in Brentwood. "They want at least three kids, so they'll need a big house," their pal explains. "That's why they're building one now."
