Kiss & Make Up! Nicole Kidman & Estranged Daughter Bella Repair Relationship

After years of emotional estrangement, RadarOnline.com has exclusively learned Nicole Kidman and daughter Bella Cruise have mended their relationship!

The Big Little Lies star, 50, has been riding high on the success of her award-winning HBO series, but now she has another reason to celebrate. Her daughter is once again part of her life — thanks to Bella’s fashionable new project.

The 25-year-old designer kicked off her own T-shirt brand, which she christened BKC — for Bella Kidman Cruise. It’s the first time Bella has publicly acknowledged her mother’s last name, and the touching tribute seems to have helped heal their fractured bond.

“Bella and Nicole have really grown closer over the past few months. They’re both focusing on moving forward with their relationship,” a family friend told RadarOnline.com.

Since Kidman and first hubby Tom Cruise split in 2001, the actress has allegedly been snubbed by her ex’s Scientology pals, and her adopted children with Tom — Bella and Connor, now 23 — were raised inside the cult and chose to live with their dad.

Kidman has admitted Bella and Connor don’t call her mom— and she was absent from her daughter’s 2015 wedding.

The “Lion” star appeared to have moved on, marrying country crooner Keith Urban, dad of her daughters, Sunday, 9, and Faith, 7. But Bella’s gesture may have turned the tide, according to insiders.

Cruise and Kidman have both taken an interest in Bella’s business, according to the pal, who claimed it’s even gotten the famous exes talking again!
