A Little Sister For Matilda!

Three months after her secret wedding, Mishs cute family gets even bigger!

Love was definitely in the air as Michelle Williams and her new hubby Phil Elverum went antique shopping in upstate New York on September 22.

Joined by Mish’s daughter Matilda, 12, and Phil’s three-year-old Agathe, the couple – who secretly wed in July – looked “happy and laid-back,” a fellow shopper tells Us Weekly. “They were very affectionate with one another.”

And it seems the two new sisters are just as close! Yep, the source reveals little Agathe tried following Matilda out to the car when the tween got tired of shopping. So cuuute!

But Agathe may not be Tilly’s only new sibling. Onlookers say Michelle, 38, seemed to be showing offa tiny bump under her overalls during the family outing – leading some to wonder if the Dawson’s Creek favourite and Phil are about to hear the pitter patter of another pair of tiny feet!
