Mila Kunis and Ashton Kutcher stepped out for a daytime lunch date at L.A. eatery Musso & Frank Grill over the weekend.

The actress was dressed in a fitted white tank top which emphasized her baby bump, and paired it with a printed maxi skirt and fluorescent yellow flipflops. She donned a pair of aviator sunglasses and looped her brunette locks in a high ponytail to keep cool. Kutcher opted for similar casual attire, donning a white tee, a cap, black pants and sneakers.

The very private couple has been seen grabbing meals in town lately, and the most recent sighting of the couple was at The Counter in Studio City, where the two grabbed hamburgers. They have also been spotted shopping for clothes at a nearby sports store where Kutcher picked up a few things.

Despite their fame, the couple has managed to keep their lives private, as no one knows for sure when the baby is due.

Recently, Kunis teased Ellen DeGeneres when she was a guest on her talk show, and that the baby is due "any day now." She did not reveal any more details after that statement.

However, Sugarscape.com is reporting that a close friend of the "Black Swan' actress has revealed to Us Weekly that the pair is expecting a baby girl in October. The source also added that "Ashton loves doting on Mila, who absolutely loves being pregnant."

While the couple has not confirmed the rumors, Kunis did say that she plans to put her acting career on hold to focus on being a mom.
