“You’ve changed my life for the better. I love you with my whole heart,” the stylist, 23, captioned the image cuddling her newborn son she shares with Louis Tomlinson.
The Los Angeles-based stylist and the One Direction singer, 24, welcomed their son on Jan. 22.
Reportedly, they are currently in a custody battle over the tot as the British pop star wants to see his son more often.
The musician purchased a 3-bedroom home for Jungwirth in Calabasas, and he’s currently renting a $21 million home in L.A. to be close to Freddie.
While he’s not asking for a DNA test, Tomlinson is petitioning for some custodial rights, including significant access to his son.
