Although, neither Grant nor Eberstein have commented on the news report, a confirmation came from Anna's mother, a Swedish politician, who spilled the beans to country tabloid Aftonbladet.
While speaking to the paper, she said, "I'm very happy to be getting another grandchild. She's due rather soon."
Although Grant and Eberstein have been together for the last seven years, their relationship often hit rough weather. The couple already has two young children, but they both have deliberately kept quiet about their family life in a bid to keep their children away from the spotlight.
However, according to whatever little is known about the couple's family, Eberstein had given birth to their first child in June 2012, a son named John. According to reports, the couple's second child is a daughter, albeit, her name has never been made public.
Grant also has a son named Felix, and a daughter named Tabitha, from his relationship with Tinglan Hong. While Tabitha was born in 2011, Feliz was born in 2012.
Fatherhood came a bit late for Hugh Grant, but it seems that the actor is making the most for lost time. Grant had made headlines in early 2014, after he went from childless to a father of three in a short span of 15 months.
