Bradley Cooper's daughter Lea bonds with Gigi Hadid's daughter Khai: Source

Bradley Cooper's daughter and his girlfriend Gigi Hadid’s daughter have a sweet bond.

After the hard launch of Cooper and Hadid's romance, a source privy to People shared an insight into the Guardians of the Galaxy star's eight-year-daughter, Lea's relationship with the supermodel's four-year-old daughter, Khai.

Sharing that the 50-year-old actor and Hadid "have a lot in common," the insider told the outlet, "Bradley’s daughter, Lea, is so sweet and gentle with Khai."

For those unversed, Hadid welcomed Khai with One Direction alum Zayn Malik, who dated the model on and off for six years.

The Maestro actor shares Lea with ex-partner Irina Shayk, who was in a relationship with Cooper for four years after first sparking romance in 2015.

The news came days after Hadid and Cooper went Instagram official on May 5, as the runway model shared snaps from 30th birthday celebrations which included PDA-filled pictures of the lovebirds.

"I feel so lucky to be 30! I feel so lucky for every high and low - for all the lessons and gifts both have brought me. To get to feel it all! I’m so lucky to be a mom, friend, partner, sister, daughter, colleague to some of the most unbelievable humans!!" Hadid captioned her social media post.
