Users online agreed there was no need for the attention seeking couple to spoil the bride's day.
"Stealing somebody else's thunder that they spent years planning is nothing short of a d**k move," one person commented.
While others told of similar situations they'd heard of in the past.
"My mother had a similar situation happen at her wedding years back. Her sister in law decided to let everyone know she was pregnant during the cake cutting... Edit: just to let you know how starved of attention she was. It was her 3rd child," said one user.
"I went to a wedding where this happened. It was the most awkward thing I've ever seen. After 2 minutes, everyone totally ignored the engagement and went back to the wedding and the new fiancees left soon after because no one was giving them attention," replied another.
Unfortunately there wasn't an update to let users know what had happened after this particular proposal.
