Scarlett Johansson  put her growing baby bump on display when she ran errands in NYC on Saturday. The actress is back on her home turf after a short stay in London earlier this year to film Avengers: Age of Ultron, the highly anticipated sequel to the first Avengers blockbuster. Scarlett's fiancé, French journalist Romain Dauriac, joined her in London, and the pair was even spotted going on a gym trip together back in June . Aside from her low-key outings, the mom-to-be has been lying low while she waits for the birth of her first child. However, Scarlett will be hitting the red carpet later this month when she premieres her latest project, Lucy, before it hits theaters on July 25.
