Rose Byrne rugs up with bub in New York winter

SHE only gave birth a few weeks ago, but Rose Byrne looked confident and healthy as she stepped out for a stroll on the streets of New York with her new bub.

The 36-year-old was snapped pushing baby Rocco in a stroller as she pounded the pavement and chatted with her pal, Dexter star Jennifer Carpenter.

Rugged up to beat the Manhattan winter, the fresh-faced Aussie actress looked edgy in a mustard jacket, skinny jeans, scarf and a beanie.

Sydney-born Byrne and her partner Bobby Cannavale revealed very few details during the pregnancy.

Cannavale broke the news of the birth on The Late Show with Stephen Colbert earlier this month, confirming Byrne had popped on February 1.

The proud dad was scant on details but revealed the “beautiful” baby’s name was Rocco.

“I had a baby on Monday, yes,” the Vinyl star said.

“You know, I didn’t do anything. We (men) don’t do anything and I’m so tired. I think I’ve gained 28 pounds (12kg) since Monday.

“I mean, I’m not kidding you. Like, this jacket fit so well, like, last Thursday. But I’ve been eating so much.”
