Rapper Lil Wayne is a father again - he's celebrating the birth of his second son in 2009.

The hip-hop star - real name Dwayne Carter, Jr. - welcomed a baby boy with R&B singer Nivea on Monday, following inaccurate reports she had given birth in early November.

According to AllHipHop.com, rapper Mack Maine updated his Twitter.com page to announce his labelmate's news, writing, "Thank God. Baby Neal was born healthy to Nivea Nash and Dwayne Carter! Thanks 4 (sic) all the blessings and support!"

The new arrival is the Lollipop hitmaker's fourth child and the second son he's welcomed this year. Actress Lauren London gave birth to little Lennox Samuel Ari in September.

Lil Wayne also has another son, Dwayne Carter III, who was born to an unidentified woman last year, and a daughter, Reginae, with ex-wife Antonia Carter.

Nivea has three other children from her previous relationship with producer The-Dream, who married singer Christina Milian in September.
