Rapper Logic is to become a first-time father.

The 29-year-old, real name Sir Robert Bryson Hall II, revealed he is expecting a baby boy with fiancee Brittney Noell in a freestyle video he dropped on Monday.

In the clip, titled No Pressure, Logic stands in an empty warehouse next to his DJ, and raps: "Surprise! It's a little baby boy, f**k TMZ they can't get the scoop on that s**t."

The baby news comes after it was reported last month that Logic and Brittney had obtained a marriage licence in preparation for an imminent wedding.

Their wedding date is not yet known, but marriage licences are valid for 90 days. It won't be the first trip down the aisle for the American star, however - he confirmed his split from ex-wife Jessica Andrea in March, 2018 and they finalised their divorce in September.

Logic and Brittney went public with their relationship in April 2018 when he flew her on a private jet to a show in Las Vegas.
