Chris Hardwick's fiancee is getting a hands-on lesson in motherhood.
Lydia Hearst just got engaged to Chris Hardwick late last year and already she's getting a hands-on lesson in motherhood.
The 31-year-old model, who is the granddaughter of newspaper magnate William Randolph Hearst, doesn't have any children of her own but in the bizarre "Commit To Something" ad campaign for Equinox gyms, she is seen breastfeeding twins.

The "Commit to Something" campaign seem to be promoting anything but fitness. Other Equinox ads include a cat lady, an orgy scene, a nearly-naked man lying in money and a super chiseled cult leader. The tagline reads: "It's not fitness. It's life."
While Hearst's breastfeeding photo is sure to raise some eyebrows, a slew of celebrities have come forward over the years in support of nursing their newborns in public.
