The “Bad Things” singer announced the news on his Instagram page on Thursday,
writing in the caption that “she’s finally here!! our little celestial seed.”
MGK did not reveal their daughter’s name but noted that her date of birth was March 27.
In his post, he shared an accompanying short black-and-white clip of his daughter’s hand clasped onto his pointer finger.
The pair announced that they were expecting in November
when Fox posted photos showcasing her belly and a positive pregnancy test on her Instagram page.
This marks Fox and Kelly’s first child together, but they are both already parents to children from previous relationships.
Fox has three children – Noah, 12, Bodhi, 11, and Journey, 8 – with “90210” actor Brian Austin Green,
, to whom she was married between 2010 and 2020.
The former couple briefly reconciled but finalized their divorce in 2022.
