Aren't these two just the cutest?!
The 7-year-old was snapped trailing behind her famous mama, carrying two wrapped presents in her hands as the duo presumably headed to a fete together in honor of the Blue Valentine star's big day.
Williams sported a brown leather jacket, skinny jeans, a polka-dot blouse and clog shoes, while her daughter looked adorable in a blue-and-green drop-waist dress. The budding fashionista added bright red sandals and a pair of hot-pink sunglasses to her chic ensemble, showing off her individual fashion sense.
E! News recently confirmed that the single mother will make her Broadway debut in the upcoming revival of Cabaret, taking on the role of Sally Bowles alongside Alan Cumming.
The blonde beauty will be filling the shoes of Liza Minnelli (the now 67-year-old star won an Oscar for her iconic portrayal of Sally in Bob Fosse's 1972 movie adaptation), who exclusively told E! News she approves of the Academy Award nominated star's casting.
"Michelle is a wonderful actress and I love Alan Cumming," Minnelli exclusively told E! News. "I'm excited to see what they will do with the show and am sure it will be great!"
So do we!
