The speculation is over.
When a svelte Halle Berry
walked onto Jay Leno's stage Thursday, the host told her she looked terrific, to which she replied: "You know, thank you for that, Jay, because that must mean that pregnancy rumors can be put to bed!"

taping tell PEOPLE that Berry, wearing a low-cut, short black dress and black thigh-high boots, also told Leno with a laugh, "I was getting a complex! Because I was like, I've got to stop with the burgers or something!"
Berry, 43, and Gabriel Aubry, 34, welcomed their first baby
, Nahla Ariela, in March 2008. The couple, who have been together since 2005 when they met while shooting a Versace ad, have made no secret of their desire for more kids.
In February, Aubry told PEOPLE Nahla "needs a sibling." The model, who comes from a family of eight kids, added, "I believe in big families." And in March, Berry said on The Ellen DeGeneres Show
that she was ready to have a second child.
Berry was another in a series of high-profile guests for Leno in this inaugural week of his 10 p.m. show. In addition to fending off pregnancy rumors, Berry told anecdotes about Nahla and meeting Aubry. Simply put, Berry gushed, "My daughter is fantastic."
