Megan Fox who recently announced she was pregnant with her second child via her publicist was spotted with husband Brian Austin Green and baby Noah over the weekend in Los Angeles.

The 27-year old "Transformers" star spent Saturday with her husband and firstborn as the brood grabbed a low -key lunch in California.

Fox, who is notoriously private about her personal lif,e hid her growing baby bump with a jacket as Green carried their 11-month old son in his arms to their car.

The star wore a grey t-shirt paired with black capri leggings and flip flops. Her long her spill on to her shoulders and down her back as she hid her bare face behind reflective sunglasses.

Meanwhile the former "90210" star wore black pants, a plain white t-shirt, and sneakers, finishing the simple outfit off with a pair of black sunglasses.

Green held baby Noah close, putting a protective hand on the back of his head as he walked down the street with the child, according to the Daily Mail.

Proving to be a caring dad, earlier this week, Green, who is also father to 11-year-old son Kassius from a previous relationship, was spotted out in Beverly Hills sticking close by his son as they enjoyed a day out together.

Earlier this month, a representative for Megan Fox told the New York Post Page Six that the actress was indeed pregnant.
