'I'm double upset!' Ashton Kutcher annoyed pal Laura Prepon kept engagement to Ben Foster a secret

Ashton Kutcher is annoyed that his That 70s Show co-star Laura Prepon didn't tell him about her engagement.

The actor, who famously kept his own engagement and marriage to co-star Mila Kunis hidden from the public for a long time, took Prepon to task during his guest co-host stint on Live! With Kelly Friday.

'She just announced this engagement, and I had to find out in the news! And she's my friend!' he exclaimed to Kelly Ripa as they were about to interview the actress about her new movie The Girl On The Train.

'And it's not just a random engagement. It's an engagement to another friend of mine!' Kutcher, 38, went on.

'So I'm double upset that neither of them told me! I got off the plane in New York like, 'What?''

Prepon, 36, debuted her engagement ring at her film's premiere in New York earlier in the week as she walked the red carpet with beau Ben Foster, 35.

Kutcher, who is expecting a second child, a boy, with Kunis, remarked that it feels 'weird' to see all his friends 'hooking up.'

Meanwhile, Prepon had a dig back at her pal who likes to keep his private life private despite his fame. 

'If anyone understands, you get it,' she told him.

'Oh, I get it,' the former husband of Demi Moore responded. 'But 'private lives' includes friends!'
