Think of when Katie Holmes walked down the aisle with Tom Cruise – it was pandemonium as they were followed everywhere, given magazines covers and bestowed the catchy nickname TomKat.

Or when Angelina Jolie started romancing Brad Pitt; jaws dropped that these two A-listers were in love and starting a family together.

But some celebrity couples are not as well known because they either dated a long time ago or their sparks were brief.

Here is a look at the luminaries people may have forgotten were an item.

And scroll down to vote on who you thought made the cutest couple that should have stuck together.

In 1995 Brad said he still had feelings for Juliette.

‘I still love the woman. There’s some real genius there,’ he shared.

‘I had a great time with her. It was one of the greatest relationships I’ve ever been in. The problem is, we grow up with this vision that love conquers all, and that’s just not so, is it?’ he said.

But in 2006 she said of the star: ‘He’s not in my universe at all now. It seems like a high-school relationship because now he’s a very famous person.

‘I look at this person that I shared a bit of history with. I hope he finds happiness because I genuinely loved him. He’s a very stand-up, good guy. … It was my longest relationship and we both lost our anonymity together.”
