The 50-year-old singer and her husband Wissam Al Mana welcomed their son, Eissa Al Mana, into the world on Tuesday (03.01.16) and the pair have been overwhelmed with heart-warming messages from their families praising them on the new arrival.
Janet's 60-year-old sibling took to Twitter to share her thoughts on the news.
Alongside a picture of a blue balloon with ''It's a boy'' emblazoned across it, she wrote: ''How exciting! @JanetJackson, Jan and Wissam just gave birth to a beautiful baby boy!!! Congratulations!!! (sic).''
And the 'That's The way Love Goes' hitmakers nephew TJ Jackson - who is the son of Janet's brother Tito - has also reached out to the star following her pregnancy, which saw him allay any concerns his aunt may have about motherhood as he claimed parenthood ''is the best''.
He said: ''Congrats Auntie @JanetJackson!!! So so happy for you & Wissan. Enjoy every minute with your greatest hit, Elissa. #parenthoodisthebest (sic).''
And it has been reported the brunet beauty is ''resting comfortably'' after giving birth.
Speaking about Janet's welfare in a statement, her representative said: ''Janet Jackson and husband Wissam Al Mana are thrilled to welcome their new son Eissa Al Mana into the world. Janet had a stress-free healthy delivery and is resting comfortably.''
Although Janet's older brother Jermaine has yet to comment on his siblings addition to the family, he has previously revealed he thinks she will be a perfect mother to her son.
Speaking before the birth, he shared: ''She'll be a great mother because she is very tough, very strict. But I tell her, 'If you need any parenting skills or baby skills, let me know because I'm the best diaper changer there is on this planet, still to this day.'''
