She's a model and actress known for her sultry style. However, Jessica Alba cut a glum and very low-key, casual figure as she touched down in New York amid legal woes over her billion dollar business.

The 34-year-old businesswoman wore muted shades of grey and black as she stepped out at JFK Airport on Monday.

The Fantastic Four star topped off her outfit with a green parka jacket and simple white trainers for comfort following a flight.

And she toted a large tasselled black handbag, perhaps used as her cabin luggage. The photos come just hours after it was revealed that Jessica's Honest Company was hit with another lawsuit.

According to WWD, Margo Smith filed a lawsuit in Missouri on March 24 seeking class action status, as she claimed that the company has used deceptive marketing to sell its products.

The woman alleges that false advertising was used for the brand's detergent, dish soap and multisurface cleaner, along with other items.

Smith claims that the company insisted it does not use sodium lauryl sulfate (SLS) in any of its products, but she alleges this is false.
