Best man completely upstages bride and groom by proposing at THEIR wedding!

It was meant to be the best day of their lives, but this couple had their wedding day hi-jacked by one of the people closest to them... The groom's best man!

In an open letter posted to Twitter, the bride revealed how the best man stood up at their wedding and proposed to his girlfrend and then proceeded to announce she was pregnant.

'My husband and I started dating, got pregnant, had a child, moved in together, bought a house and got a dog in that order,' the letter started.

'Our friends and family have asked us for years why we weren’t married yet. We always pushed it off to build better lives. We’ve done really well for ourselves and finally reached a point where we could afford a huge blowout wedding to celebrate our lives with everyone we know and love. My husband’s best friend, “John”, was the best man/officiant.'

'The setting was beautiful, everyone seemed happy, our families were overjoyed. My mum may have used the phrase “Hallelujah” a few dozen times. The entire atmosphere felt moving.'

'So moving in fact, that John stopped mid-ceremony to propose to his longtime girlfriend, “Jane”, and reveal her pregnancy.'

'I couldn’t even hear the vows my husband wrote or the rest of the ceremony over the noise of Jane’s happy sobs, her very surprised family who were also guests and people seated nearby congratulating her. Even the videographer cut to her frequently during the ceremony and you can’t hear anything over the chatter,' the bride continued.

'When John gave his toast, he apologised for being caught up in the moment and then proceeded to talk about his and Jane’s future with nary a mention of us.'

'John even went out of his way to ask the band for a special dance for just him and Jane on the dance floor.'

'I’ve never been an attention hog, and I wouldn’t even have minded if he’d proposed after the ceremony, but weeks later I am still seething.'

'I am so shocked and angry that I keep asking myself if this is real life.'

The relationship with Jane & John has been tense since the wedding, with friends advising the newly weds to just 'get over it.'

'My husband has joked that he’ll resume his friendship when John and Jane give him a $40,000 check for their half of the wedding' she concluded.

Many people have come out in support of the couple saying the behaviour of the best man was simply appalling, but what do you think?
