Naomi Watts took her 13-month-old son Alexander ‘Sasha’ out for a walk today in Brentwood. Thanks to Ev, we now know she was on a walk with friend Rebecca Rigg, who is married to Simon Baker. By the end of the walk, Sasha had fallen asleep in his stroller. Naomi is definitely making sure to stay active – she’s always out jogging or taking Sasha out to play. She’s due this winter with her and fiance Liev Schreiber’s second child.
