Get ready to meet the latest contender for cutest baby in Hollywood...and possibly the biggest.

Miranda Kerr and Orlando Bloom have welcomed a baby boy—and, according to her family, the kid is a monster, tipping the scales at nearly 10 pounds.

Here are the latest details...

Per Kerr's local newspaper, Sydney's Daily Telegraph, the super-sized bundle of joy arrived last Friday, and despite his size, the petite Kerr (as well as her Lord of the Rings hubby) are doing "very well," according to a family friend.

The tyke, whose name has not been released, is the first for Kerr, 27, and Bloom, 33.

Already, the folks in Kerr's native Australia are abuzz, including the mayor of her hometown of Gunnedah.

"Everyone is really excited. She still has strong family links here and we are very proud of her," said Mayor Adam Marshall. "We would like to see Miranda, Orlando and the new bub in Gunnedah."

Marshall says the town is working on a baby (bubby?) present, with contenders including "Koala Capital of the World" T-shirt. Just make sure to send an XL.
