The 41-year-old was seen at New York Fashion Week earlier this month with no noticeable baby bump, but she was spotted sitting front row at the Tommy Hilfiger show wearing loose fitting clothes.

Thurman has two children, daughter Maya, 13, and son Levon, 10, with ex-husband Ethan Hawke.

She and Busson, 49, began dating in 2007. The two had a brief split in 2009, but have been together since, according to People.

The "Kill Bill" actress will soon appear in a five-episode arc in NBC's new drama "Smash."
