Former star of the US version of The Office Jenna has revealed that she gave birth to a baby girl on 25 May.
The new arrival, who is called Harper Marie Kirk, is Jenna and her husband Lee Kirk's first daughter and is a younger sister to their two-year-old son Weston Lee.
"We are pleased to announce the birth of our daughter Harper Marie Kirk," the couple told E!. "The family is doing great. We are happy, healthy and sleepy."
In the run up to the birth Jenna told People about how she been preparing her son for the arrival of his younger sibling.
"My big pregnancy craving with him was Menchie's frozen yogurt and there is a Menchie's across the street from where I delivered. After he was born, there is a picture of me eating Menchie's [and] holding him," she said. "We showed him the picture… and I said, 'Mommy has to go to the hospital to get the baby out and you can come visit me.'
"He said, ‘After the baby is out, Mommy gets to eat Menchie’s'. And I said 'That's right … do you want to come to the hospital and have Menchie's with me?' And he said yes!"
Jenna and Lee Kirk have been married for four years
Jenna, who confirmed her pregnancy in February, said that she is fully prepared for the increase in parenting responsibilities.
"Everyone's telling me one plus one does not equal two," she said. "One plus one feels like four."
