(LOS ANGELES) -- Hugh Grant is a dad for the third time. The About a Boy star and his girlfriend, Swedish TV producer Anna Elisabet Eberstein, welcomed a son back in September, according to a copy of the birth certificate obtained by Us Weekly.
The couple reportedly tried to keep the birth a secret, but the document confirms the baby was born at London’s Queen Charlotte and Chelsea Hospital and lists Grant as the father. The baby’s first name isn’t mentioned, but the actor is listed as the father under his full name, Hugh John Mungo Grant.
The magazine reports Eberstein was pregnant at the same time as Grant’s on-again-off-again girlfriend Tinglan Hong, who gave birth to her second child with Grant, last month. The couple welcomed a daughter in 2011.
Us Weekly could not confirm the status of the actor’s current relationship with either Eberstein or Hong.
Grant will be seen next in The Reluctant Professor, a romantic comedy about an Oscar-winning writer in a slump. The film co-stars Marisa Tomei and Allison Janney and is set to hit theaters sometime this year.
