Ashton Kutcher might have provided fans a glimpse into Mila Kunis' sexy post-baby body secret as the "Two and a Half Men" star was snapped lugging around a workout device after a romantic dinner at in Toca Madera on West Hollywood, Monday.

"Hubby Ashton was charged with carrying the haul, which included a pretty superfluous looking workout tool, which according the the packaging 'increases range of motion and flexibility', increases circulation', and is 'ideal for warming up the body before physical activity and for recovery after,'" said Daily Mail.

The device was apparently a gift from Ashton Kutcher, perhaps his way of contributing to Mila Kunis' goal of having a slimmer post-baby body, as the British publication noted, "The box still bore evidence of hastily torn wrapping paper, while Ashton's bag was full of further wrapping and possibly other hidden delights."

Just a week ago, E! News reported that Mila Kunis seemed to be back to her pre-baby body. Mila Kunis and Ashton Kutcher welcomed Wyatt Isabelle in October 2014.

"She flaunted her slim post-baby bod in a white button-down crop top by Native Youth teamed with a pair of black skinny jeans and matching flats," said E! News.

"Kunis, who is known for her laid-back style, wore minimal makeup and swept her hair to the side, accessorizing with dainty gold jewelry, in addition to what appears to be her thin gold wedding band," it added.

Mila Kunis and Ashton Kutcher tied the knot during the July 4th holiday and they also went on a honeymoon by getting into the RV to tour the country as baby Wyatt tagged along.

During an interview with Jimmy Kimmel's show, Mila Kunis shared her post-baby body weight loss secret.

"Breastfeeding is like working out," she said. "I am very active. I hike almost every day with her... I strap her in a papoose and away we go."
