Tom & Gisele's Playdate

It looks like supermodel Gisele Bundchen has babies on the brain! The Brazilian beauty was spotted frolicking in a Boston Park with boyfriend Tom Brady, 31, and his 1-year-old son John Edward Thomas on August 27 (Mom is actress Bridget Moynahan).

"She was looking after Jet and they were laughing together," a pal of the couple tells OK!.  "She sees how great a father Tom is and it is making her want to settle down and start a family herself."

Gisele, 28, has already moved in to the New England Patriot quarter-back's home in Beantown and was recently seen buying an antique armoire for their bedroom on Aug. 19.  According to the friend, "It won't be too long before the two say 'I Do.'  They've been slowing progressing their relationship and plan to have a big wedding both in the States and in Brazil."

But don't think Tom is a part-time dad!  while baby John currently calls the left coast home with mom, Tom is already making plans to be closer to his little patriot.  Brady recently purchased a giant 3-acre plot of land for $11 million in Brentwood, Calif., where he plans to build a home for him, Gisele and his son.
