Jena Frumes penned a note to her four-month-old son, Jason King, after her unexpected split from his father Jason Derulo.


Hours after Jason announced their split on Twitter, the 28-year-old fitness model shared an image of herself holding hands with her son in a dark room. 


She captioned the photo: “I love you bubsyyy. I promise to give you all the love I never had, you deserve the world baby boy.”



While she has yet to publicly address their breakup, Derulo, 32, confirmed their separation over Twitter. 


The announcement shocked fans as Frumes had just wished Jason a happy birthday on social media less than 24 hours prior, saying she would “love him forever.”
