Briana Jungwirth, Louis Tomlinson's former girlfriend and mother of his six-month-old son, is reportedly not happy with the singer's new girlfriend Danielle Campbell. Jungwirth, a Los Angeles stylist took to social media to slam Campbell after she and the One Direction singer were pictured spending time with their son Freddie Reign on the beach in Malibu, California.

"You can pretend all you want but you will NEVER be my baby son's mother," Jungwirth wrote to her 41,000 followers on Twitter.

Earlier in the month, the 24-year-old singer, who is currently seeking joint custody of Freddie, was forced to issue a statement fearing for his son's safety with the constant "levels of paparazzi and media intrusions".

"The persistent and increasing levels of paparazzi and media intrusions into Freddie's life of late are not only posing potential security issues but are also crucially invading the privacy to which Freddie is undoubtedly entitled as a child. The levels of paparazzi attention on Freddie are intolerable and completely unjustifiable," Entertainment Tonight quoted a letter by Tomlinson's representative as saying.

"Louis appreciates, respects and values his relationship with the media and we hope he and his son are afforded the same respect on this matter," the letter added.

Earlier, Jungwirth had also taken to Twitter to tell the public that their "negativity and venomous attacks" on her and her son were a waste of time.

"To all those who feel the need to make disparaging, hateful and inappropriate comments concerning me and my son Freddie – I am sincerely sorry that you all have chosen to focus your time and attention on my life and the life of my son. Surely you must have better things to do than pry into the personal life of a single mom and newborn child."

"I am confident that in the days and weeks to come, you all will find that your negativity and venomous attacks were little more than time wasted. In the meantime – I am hopeful that you will all respect my son's privacy and find it in your hearts to discontinue the overwhelmingly inappropriate comments about me, my family, and most importantly my son Freddie. Thank you," she added.
