Bradley Cooper and Suki Waterhouse reportedly have a "hippie arrangement" of commitment.
The handsome actor and British model have been dating since last year after meeting at the 2013 Elle Style Awards in London.
They regularly flaunt their romance while out and about or at A-list events, and recently a photo showing them wearing matching rings on their wedding fingers sparked rumours. The couple are thought to have taken their long distance relationship to the next level.
While Suki, 22, has yet to tie the knot, Bradley was previously wed to actress Jennifer Esposito.
"There's been some sort of intimate thing go down between the two of them. It's been very private and didn't involve a formal blessing," a close pal told British magazine Look. "Brad's been married before, so he's not setting a huge amount of store by making it 'official'. Suki's so head over heels - and young - that she's totally cool with this more hippie arrangement."
Bradley, 39, is said to be the one who decided on wearing the jewellery. It may not mean they're husband and wife, but it's enough to show their dedication to one another.
"He presented Suki with a ring and he's wearing one, too - admittedly on and off, but it's still a gesture that they're both off the market," the pal noted.
Each party have previously spoken about their dreams of having a family, so it is thought the future will be a busy one for the couple.
"They're joined at the hip and whenever you see them together Suki's on another planet because she's so happy," an insider added.
