Scarlett Johansson looked stunningly amazing five weeks after giving birth to her daughter Rose. She was spotted in New York City last Wednesday looking absolutely beautiful as she showed off her slim post-baby body.

The 29-year-old "Lucy" star looked like she worked really hard to regain her highly coveted curvy figure. She was heading to the gym wearing fashionably comfortable black leggings, which fit her legs like second skin, and a form-fitting navy hoodie. Because of the skin-tight leggings, her toned calf and svelte physique were on full display.

She was photographed leaning up to share a kiss with her handsome fiancé Romain Dauriac. While they were making out, Dauriac gave Scarjo's pert butt a relatively affectionate squeeze as he leaned in to get more kisses from his wife-to-be.

The highly romantic couple actually welcomed their first child together, baby Rose Dorothy, just last month. A source told Us Weekly that their baby's name, which looked like it was taken straight out of "Golden Girls," was just a pure coincidence. They did not really intend to name their daughter after one of the show's characters, though the couple might not have anything against that either.

Scarlett Johansson and Dauriac only got engaged last year after dating each other for 10 months. Scarjo used to be married to Ryan Reynolds and was with the "Green Lantern" actor for two years. They decided to get a divorce in 2010.

Scarjo shared with Vogue that she was very happy that she was dating someone who was not from the showbiz industry. She said, "It is easier, but it's more than that. We do different things. He's in the whole art-scene world. So, it's nice because we can enjoy each other's worlds, but we don't have our crazy conflicting schedules and all that other stuff to contend with."
