Tabloid reports have claimed that the pair are on the rocks as Marsh is allegedly struggling to be apart from Lomas, who has made a temporary move to the US to search for acting work there.
Speculation over the pair's future continued today (March 1) as pictures emerged showing Marsh out in public without her engagement ring.
However, writing on Twitter, Marsh commented: "Annoyed now, just to say these latest stories in press are out of nowhere. I will be correcting in my column, but this latest ring story is a joke!
"I was out at Dancing On Ice with Jamie's sister!!!! I had earlier applied cream to my person and forgot to put it back on! Why? Must I ALWAYS make sure my rings are on just in case someone wants to talk crap! For f**k's sake! #laughable."
She continued: "In fact, there is a pic of me earlier that same day wearing a white oxo jumper and clearly I have my ring onnnnnn!!!!!!! (sic)"
Marsh and Lomas, best known for their roles as Corrie's Michelle Connor and Hollyoaks' Warren Fox, have been an item since 2008 and have a young daughter Polly together.
