The Love Actually star quietly welcomed his third child, a son, with Swedish TV producer Anna Elisabet Eberstein back in September, Us Weekly reports.

Grant welcomed a son named Felix in February 2013 with Tinglan Hong. He and Hong, whom Grant called a "fab mum," also have a daughter together, Tabitha Xaoi Xi Hong Grant, who was born in September 2011. Although at the time their union was described as "fleeting," the pair reunited not long after.

"I can't pretend like it wasn't a surprise, but it's a very nice surprise," Grant told Ellen DeGeneres of his first child in April 2012. "In fact, the baby's name in Chinese means 'happy surprise.' It is quite life changing, I recommend it." 

Grant, who famously dated Elizabeth Hurley for 13 years, will next star in the romantic comedy The Reluctant Professor.
