Recently, the 40-year-old actor was spotted with his stunning wife at the Hollywood premiere of ‘Doctor Strange,’ where they were practically inseparable on the red carpet.
Reports suggest that the happy couple announced the news on the red carpet at the premiere.
The 38-year-old English avant-garde theatre and opera director claimed to have hidden a small baby bump under her stunning floor-length black dress at the bash, while Cumberbatch looked dapper in a dark velvet suit.
The pair previously welcomed their son Christopher in June 2015.
Meanwhile, despite his busy work schedule, the actor, who is already familiar with playing detective, recently hinted that he would like the chance to take on the role of James Bond.
Speaking to GQ magazine he said, “I think people are obsessed with other people being Bond at the moment, so the heat’s off me.”
A self-confessed 007 fan, Sherlock continued, “I can wear a suit and I can fight. I can raise my eyebrow, but that’s not what it takes to play Bond.”
“They might want to go in very different directions, who knows? It would be fun though,” he added.’
