Rowan Atkinson is set to become a father for the third time at the age of 62.
The English actor is expecting his first child with his girlfriend, actress Louise Ford, who is 29 years his junior.
He shares two children with ex-wife Sunetra Sastry - 24-year-old son Benjamin, and 22-year-old daughter Lily.
A source said: "Rowan and Louise are over the moon and can't wait for their new arrival".
The Oxford educated actor, comedian and screenwriter met Miss Ford - best-known for playing Kate Middleton in the Channel 4 comedy The Windsors - when they were in a West End play together. The reports come after Louise was spotted with a large baby bump while shopping in North London on Sunday.
Odd-even gets NGT nod; no exemptions for two-wheelers, women, govt servants
Resorting to the odd-even scheme as a stop-gap arrangement will only work to disillusion the public from its marginal efficacy. The takeaway is fairly simple: Do not attempt easy solutions for complex, seemingly intractable problems.
Rowan Atkinson is already a father of two, Ben, 23, and daughter Lily, 21 from his ex-wife Sunetra Sastry whom he divorced in 2015.
The news comes after a Daily Mail report last month that Lily, a burlesque dancer, had chose to ditch her father's surname, taking on the maiden name of her mother instead.
Atkinson, who attracted nearly 19 million viewers in his role as Mr Bean at its peak, has amassed a fortune of an estimated £70million. An insider told Daily Mail at that time, "It's a real mystery". The burlesque dancer ditched her father's surname and adopted the maiden name of her mother, Sunetra Sastry. I hope she hasn't fallen out with her dad.
His silent Mr Bean character - first seen in 1990 - has appeared in three hit movies so far.
