Gigi and Bradley have been romantically linked since October 2023. 

Last year it was reported the smitten actor was ready to take their romance to the next level and pop the question, with insiders claiming he is ‘determined’ to marry the supermodel. 

In January, it was reported that Bradley and Gigi are getting ‘serious’ but aren’t in a ‘rush’ to get engaged.

The Hollywood hunk and the model are ‘very happy’ in their relationship and feel like getting engaged would be a ‘big step,’ a source told People.

This comes after Gigi made a big show of support for her boyfriend’s latest business venture amid reports that she is ‘in love’ with him and that ‘their relationship is a big priority for her.’

Bradley and Gigi are ‘serious about each other, but an engagement would be a big step,’ the insider revealed.

‘Neither are looking to rush anything, but that’s not to say they’re not very happy together,’ the source continued.

They were also joined by Gigi and Bella’s dad Mohamed Hadid, 76, and his Russian model girlfriend Keni Silva, 41

The insider also noted that both of their ‘families spent time together, and so do their kids. It’s very sweet.’

About their connection, the source said that the model ‘has a free spirit personality’ and ‘brings out a fun side of Bradley.’

‘They’re very happy,’ another source added. ‘They are busy with work but also prioritize their relationship and daughters.’

Bradley shares daughter Lea De Seine, seven, with his ex-girlfriend, supermodel Irina Shayk. The pair were in a relationship for four years before they broke up in 2019.

He previously dated and was married to actress Jennifer Esposito for less than a year before they divorced after just four months of marriage in 2007.

Meanwhile, Gigi shares four-year-old daughter Khai with One Direction alum Zayn Malik.

She dated the singer-songwriter for nearly six years before they called it quits in October 2021.
