'Transformers' star debuts her growing baby bump
It’s been a long 24 hours for Megan Fox.  Last night (December 12th) she walked the red carpet at This Is 40’s Hollywood premiere, showing off her post-baby body in a figure-hugging Roland Mouret.

This morning she announced nominees for the 70th Annual Golden Globe Awards with Ed Helms and Jessica Alba.

The premiere, held at Grauman’s Chinese Theater, drew a cast of thousands.  Paul Rudd, Leslie Mann, Chris ODowd, Lena Dunham, Albert Brooks, Maude Apatow and Jason Segel were joined by Ava Sambora (yup, she’s part of the cast), Heather Locklear, Finola Hughes and Danica McKellar (Winnie!!!).

Fox has been fielding questions about her son, born in late September.  Noah Shannon (dad is Fox’s husband, Brian Austin Green) and mom listen to Michael Buble’s Christmas beats. 

“My baby likes him too so we’re into that — he’s a smooth crooner,” Fox told Us Weekly at a press junket.

The 26-year-old is re-thinking her future roles with Noah in mind.

“I’m going to be more cautious about choosing films,” Fox told the Mirror.  “I’m already thinking about when he’s in school and his friends are going to be showing him my photo shoots with me in a bikini and he’s going to be horrified.”
