A second son has arrived for Hong Kong Cantopop singer Hacken Lee.

Hacken's wife, Emily Lo, gave birth to the 3.3 kg baby boy named Rex by Caesarean section last week. The second-time father emailed the media to share his joyous news earlier this week on Tuesday.

In the email, he wrote, "Like the last time when 'big boss' (his two-year-old firstborn, Ryan) was born, I was in the delivery room to support [my wife] for the birth of the 'second boss' (Rex) last week."

He shared that both mother and child are fine. Emily was discharged last Wednesday.

The 42-year-old married his longtime girlfriend Emily, who is also 1992's Miss Hong Kong, in 2006. The actor-singer will resume work in May.
