The comedian took to Twitter to announce the news along with a happy message that her "first grandchild" is here.
"My daughter chels – jake – and skylar rose my first grandchild !!! #love #life #NANA" Rosie tweeted excitedly along with a picture of the family on Wednesday afternoon.
The photo, shown above, appears to be taken beside Chelsea's hospital bed. Rosie revealed that she anticipates her granddaughter to call her "Nana."
As Radar readers know, Chelsea, 21, and Rosie have a tumultuous past, with the funny woman's daughter publicly bashing her.
Chelsea's pregnancy has helped mend the mother-daughter duo's relationship. Radar reported that the 21-year-old new mom is currently undergoing a nasty divorce battle with her ex, Nicholas Alliegro.
Chelsea moved on from her ex to her baby daddy, Jacob Bourassa. As Radar readers know, Jacob, a Wisconsin native, has a criminal past. In 2013, the father of Rosie's first grandchild was found guilty of endangering safety by use of a dangerous weapon and criminal damage to property.
Jacob was sentenced to 10 days in jail, 50 hours of community service and one year of probation for the crimes.
The couple first revealed the baby's gender in October. The new bundle of joy was given a due date in January 2019, so little Skylar was born at least a couple weeks early!
