Sara Cox: Pretty & Pregnant!

After picking up some bargains at the Top Shop in London, British Radio 1 DJ Sara Cox was spotted shopping with her 1-year-old son Isaac at Marks & Spencer on Wednesday (September 30).

The newly expectant mom looked maternity chic in her black skinny jeans, brown leather boots and a green handbag while pushing her son in a Maclaren stroller.

Just two weeks ago, Cox, 34, took to Twitter and announced her third pregnancy:

how terribly modern of me to say this on twitter! want to share with you just before I do it live on air: im pregnant & over the moon xxx".

Sara is currently expecting her second child with Isaac's father, 32-year-old advertising executive Ben Cyzer. Sara and her ex-hubby Jon Carter have a 5-year-old daughter, Lola.

Congratulations to the Cox-Cyzer family!
