American actress works that new mummy glow as she strolls around New York with her family

OLIVIA Wilde announced the safe arrival of her baby boy on Twitter last week.
And not keen to keep him cooped up indoors for long, the American actress and her fiancé Jason Sudeikis took little Otis Alexander for his first trip out.

Strolling around New York in the sunshine, the happy trio enjoyed the sights of the city as they showed off their tot for the first time in public.
Cradled close to Olivia, the newborn appeared to be peacefully resting in his baby carrier with only his teeny legs and arms on display.
The Hollywood beauty was also full of smiles as she proudly looked at her baby boy and showed him off to the world.
Going without make-up, the 30-year-old dressed her post-baby figure in a pair of simple denim jeans and a black t-shirt.

Partner Jason also stayed close by as he enjoyed the day out with his new family member and wife-to-be.

Only too happy to share her son's birth with the world, Olivia wrote online: "Ladies and gentlemen, Otis Alexander Sudeikis has LEFT the building! (I'm the building)."
The brunette star and Jason announced they were expecting their first baby together in October 2013.
