TOBEY MAGUIRE AND JENNIFER MEYER EXPECTING SECOND CHILD

Jen is approaching her second trimester and she's due in early October. "Jen and Tobey are over-the-moon happy," a friend of the couple reveals. "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 insider says that Jen and Tobey 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," her friend reveals. "She had an easy pregnancy last time around, so this time it should also be a breeze." The couple is in the process of building their dream home for their expanding family on a recently purchased lot in Brentwood that cost nearly $10 million! "They want at least three kids, so they'll need a big house," their pal explains. "That's why they're building one now."
