There have been rumors that Julia Roberts could be expecting another child, but the August: Osage County star shot them down during an appearance on The Late Show with David Letterman.

The proud mom, 46, talked about how her kids twins Phinnaeus and Hazel, 9, and Henry, 6, are gearing up for the holidays when Letterman brought up the possibility of having another.

"Have you thought about adding more to the group?" he asked and she replied, "Oh sure.” Letterman asked, “Any chance?" to which she responded, "No,” The Mirror reports.

As we previously reported, Roberts was photographed wearing a baggy sweater around her husband, Danny Moder’s parents' house. The loose clothing prompted rumors to start about a possible third pregnancy.

Her rep, however, denied the rumors right away.

Uma Thurman, Mariah Carey and most recently, Halle Berry, are just a handful of celebrities who have given birth in their 40s.

Roberts attended the New York City premiere of her film August: Osage County on Thursday.
