The Geordie Shore star sparked speculation of a split from Ricky when she tweeted on 30 August: "I couldn't of ever imagined what this day would bring. My heart is broken."
Fans were quick to presume the tweet was about Ricky, but Marnie's friend Chloe Goodman has now confirmed that wasn't true.
Reacting to a newspaper report that Marnie and Ricky had split, former CBB star Chloe said: "This tweet was about her puppy Smith not Ricky ... Her puppy had a horrible accident @MarnieGShore."
Marnie retweeted the message and fans were quick to send the reality star their well wishes on poor Smith. She has not clarified what happened to her pooch.
Chloe's tweet came as Ricky also hit out at split speculation, telling fans: "All stories are false. Until you get a quote from me personally, don't believe what you read. Unless the story comes from my mouth then don't believe a word."
He also replied to one Twitter user who suggested Marnie had cheated on him, replying: "No she didn't. It's lies."
Ricky proposed to Marnie in June, while she was filming the Geordie Shore finale in Greece. The proposal was captured on camera to air in an upcoming episode.
