Lauryn Hill has become a grandmother.

The 41-year-old singer's son Zion Marley and his girlfriend welcomed their son Zephaniah into the world over the weekend.

Zion's father Rohan Marley took to social media to celebrate the baby's arrival, citing a passage from the bible: ''In that day it shall be said to Jerusalem, Fear thou not: and to Zion, Let not thine hands be slack.''

And Zion also took to his own Instagram page to gush about the new arrival, adding: ''If there EVER was a question who I do it for... #myson (sic)''

Lauryn - who found fame as a member of the Fugees - loves to perform but disappointed her fans when she turned up two hours late to a concert in Atlanta because she needed to ''align her energy''.

She shared at the time: ''I don't show up late to shows because I don't care. And I have nothing but Love and respect for my fans. The challenge is aligning my energy with the time, taking something that isn't easily classified or contained, and trying to make it available for others. I don't have an on/off switch. I am at my best when I am open, rested, sensitive and liberated to express myself as truthfully as possible. For every performance that I've arrived to late, there have been countless others where I've performed in excess of two hours, beyond what I am contracted to do, pouring everything out on the stage.

''Because I care so deeply about the artistic process, I scrutinize, have perfectionist tendencies, and want space made for spontaneity, which is not an easy process, with the many moving parts on the road. Some days we are more successful than others re time. However, the vitality that is infused into the performances is always appreciated by the audiences, who may not know exactly what it took to accomplish. (sic)''
