The 'Sherlock' actor has looked towards Shakespeare as inspiration for his son's name.
Benedict Cumberbatch has reportedly welcomed his second child with wife Sophie Hunter.
It's thought the 'Sherlock' star's partner gave birth to a baby boy on March 3 at the luxurious Portland Hospital in London, where a room costs a whopping £1,200 a night.
Apparently, the couple looked towards Shakespeare as inspiration for his son's name and have chosen to call him Hal, which is thought to be the nickname given to the famed playwright's hero Henry V, the Daily Mail newspaper reports.
The news comes after Benedict and Sophie announced they were expanding their brood back in October.
Meanwhile, the 40-year-old actor - who already has 21-month-old son Christopher with Sophie - previously spoke about how much fatherhood has helped his career.
Benedict said: "Lots of people, especially women, get told, 'Oh parenthood is really going to affect your career - and it does, but for the better I think.
"I know I'm in a very privileged position in my career but I think everyone, even if they're in a challenging time in their life, draws strength from their children. They are your inspiration. It adds to your work, it never takes away."
According to the actor, having children and a wife to go home to makes him a "very homely" person.
He shared: "I don't think of myself as this huge Hollywood star. I have a new family and I have close friends who have known me since I first started and don't think of me like that.
"They're always happy to remind me who I am, which is good. I don't find it difficult to stay grounded. Every time I come back to London, I love the feeling - it's my hometown and I'm very happy with my creature comforts. I'm actually quite a homely person, although I still enjoy being on the red carpet."
