A newly brunette January Jones spent yesterday out and about in LA with her son, Xander. The actress hasn't been afraid to experiment with her hair color in the past, and even debuted pink highlights earlier this year during her break from filming Mad Men. It's unclear whether January went dark for an upcoming role or just for fun, but Xander didn't seem fazed by his mom's new look, flashing a smile as she carried him from their car.
Since January gave birth to Xander in 2011, her son has been her constant companion, and the pair are often seen traveling together and running errands in their LA neighborhood. Earlier this month, January took time out for a ladies' luncheon, joining fellow celebs including Jennifer Aniston and Gwen Stefani at the CFDA/Vogue Fashion Fund's fashion show at the Chateau Marmont.
