The 49-year-old actor and Gigi, 28, were recently spotted holding hands on the streets of London, after months of speculation about their relationship status, and an insider has now revealed that the celebrity duo have a "natural connection".

A source told 'Entertainment Tonight': "Gigi and Bradley are in love."

Gigi and Bradley's burgeoning romance has been described as "easy, fun, and normal".

A second source said: "Things have continued to blossom between Gigi and Bradley and have gotten serious," a second source says. "Everyone around them sees their natural connection. Their relationship is easy, fun, and normal.

"They bond over family, friends, conversations about life, parenting, living in the public eye, humor, and more. They have a synergy and understanding with regard to all these things and it connects them in a deep way."

Last year, a source claimed that Bradley felt "excited" about getting to know Gigi.

The Hollywood actor loves spending time with Gigi and she's "exactly his type".

The source told "Bradley is excited about getting to know Gigi.

"He hasn't felt this excitement about a woman in a very long time.

"They are taking it slow, but he's very into her. She is exactly his type."

Bradley and Gigi - who previously dated pop star Zayn Malik - were also said to be "having fun" together, in spite of their age gap.

A second source said at the time: "Bradley is eager to date again and be in a relationship.

"He loves all that comes with it and Gigi is beautiful and she gets it, she is really cool and knows her way around relationships like this with famous men, so they are both having fun."
