The world is still waiting for its first glimpse of Megan Fox and Brian Austin Green's baby son Noah, with the couple leaving fans guessing as to what the 12-week-old baby looks like. Fox again stopped at home to care for the tot this week, with Green tasked with taking his son, Kassius, Christmas shopping in Los Feliz, reports the Daily Mail.

The former Beverly Hills 90210 actor headed out with his eldest son to pick up some gifts for the family, buying an Atari flashback, a Nutcracker figurine and wrapping paper. The shopping trip came shortly after Fox appeared on the Ellen Degeneres show, speaking about baby Noah's appearance for the first time. "He looks, I would say 70 per cent like Brian. He was his identical twin when he came out and recently he's been getting chubbier and everyone's like oh, he's so chubby now he looks like you and I don't know how I should take that," she told the host. The Transformers star also discussed how she kept Noah's birth a secret for weeks because Reese Witherspoon went into labour with her son Tennessee the day before. "She went into labour the day before I did and all of the paparazzi followed her to Santa Monica and so when I went into labour I went to Cedars [Sinai hospital] and nobody cared or knew or was there and so I got in and out."

Brian and Megan married in an intimate ceremony in Hawaii in June 2010 after a six year relationship. Kassius is Brian's son from his previous relationship to the actress Vanessa Marcil.
