Reports emerged claiming that the 44-year-old visited Mone at the Dorchester Hotel on February 16, taking with him champagne and roses to her suite, despite being pictured with on-off partner Elizabeth Hurley a few days beforehand.
Warne took to Twitter to blast false reporting, which the Daily Mail claims is aimed at the rumours of the four-hour tryst.
He wrote: "Just read some more ludicrous & laughable reporting on me, what an absolute load of rubbish! Whatever, time to rack up the air miles again."
Reports have claimed that Warne and Hurley are trying to rekindle their romance following their split last year.
