Baby Boy Hudson-Bellamy has a couple ounces on Harper Seven Beckham!

Kate Hudson has yet to reveal the name of the son she and fiance Matt Bellamy welcomed in L.A on Saturday night -- but the actress did share her happy news with pals in a short email.

Hudson, 32, revealed that her newborn weighs 7 lbs. 12 oz. (Victoria and David Beckham's daughter Harper Seven, born Sunday morning in L.A., weighed 2 ounces less.)

And the Oscar-nominated star doesn't want her pals to gift her with fancy strollers or couture jumpers. In lieu of gifts, she asked for "celebration trees" to be planted via Barcham Trees, a British service used by Queen Elizabeth herself. She similarly asked for tree-plantings instead of pricey presents at her June 5 baby shower in Malibu, attended by folks like Courteney Cox, Rachel Zoe and Nicole Richie.

As previously reported at Us Weekly, Hudson and Bellamy, 33, plan to spend their first days with their new son at the Muse rocker's London home while he records a new album.

The little boy's big brother is Ryder, Hudson's 7-year-old with ex-husband Chris Robinson of the Black Crowes.
