Wiig continued, "I don’t know if I truly appreciated my mom the first 45 years of my life. But this year I’m feeling especially grateful for her advice, her love. I’m so thankful for all the things she’s taught me, like preparing to be a mom myself." She added, "Things like breastfeeding,” before lifting up a plate of cooked chicken breasts, saying, “Babies love that chicken, she would always say that."

At the time, in 2016, the two were seen showing off some PDA in Kauai, Hawaii, and a source exclusively revealed to PEOPLE that the couple had been “dating for a few months.” "They’re really happy together," the source added.
