Yep, that's what happened on New Zealand's TVNZ Breakfast, in an epic faux pas which saw the show's hosts honour the infamous killers after mistakenly thinking they were a regular couple whose kids had written in to the show on Wednesday morning.
Check out the clip below:
The couple, who lived in Gloucester in the English countryside until their arrest in 1994, have gone down in history as two of Britain's most notorious serial killers.
The West's were known to have killed at least twelve women who they buried under their patio, including their own children.
But when a photograph of them was sent into Breakfast's daily 'Today's The Day' section, where hosts, Jenny-May Clarkson and Indira Stewart, usually celebrate events sent in by viewers, they had no idea who the couple were, leading to a disastrous live celebration of their 'love'.
"Francis and Violet Eastwood celebrate their 30th wedding anniversary," said Jenny as a famous picture of the killers appeared on the screen.
"I love it," she went on.
"This is their children's favourite photo of them taken on their on honeymoon way back in 1990".
As she spoke, Sister Sledge's We are Family was faintly playing.
"Check out that afro," Stewart said, as the segment continued.
"From your adoring children Dan, Rachel and Edwin - they say you are the most caring parents they could ask for and are looking forward to celebrating with you today," she chimed on top of the song.
Before rounding off: "Here's to another 30 years."
Right after the news, the pair were back to apologise for the mishap, with Jenny saying that the person who had send in the image had done a "really awful thing".
"Someone has taken advantage of our sleep deprivation and actually it was a really unkind 'joke' to be honest. We apologise unreservedly, we own our responsibility.
"However, to that person, that was a really awful thing to do on such a significant day," she said.
A TVNZ spokeswoman also went on to issue an apology after the prank aired, saying: "An image of Rosemary and Fred West was sent into the Breakfast team along with a false backstory for our Today's The Day segment.
"Unfortunately this was not caught before going to air," she wrote in a statement.
"We sincerely apologise to our viewers who saw this error on screen. Jenny-May spoke to our viewers as soon as the mistake was realised and noted that we take responsibility for getting things right, and we are now adding extra steps to make sure we are not taken advantage of in this way again.
"We are disappointed someone chose to mislead us when this daily segment is an opportunity for our audience to share their positive news."
