In an interview last month, Warne's ex Simone Callahan told a women's magazine that their reconciliation crashed after he mistakenly sent a text message inviting 'his lover' into his London apartment.
The Woman's Day magazine claimed the ''other woman'' was Jemima, also the ex-girlfriend of actor Hugh Grant.
However, 38-year-old retired soinner has rubbished the report saying he and Jemina were ''just friends''.
''There's absolutely no truth in that one whatsoever. We're good friends, friends with the family and that's it,'' he said.
''Hopefully that all clears it up.'' Warne also said he had no interest in perpetuating a feud with Simone, from whom he divorced in 2005 after claims of infidelity only to attempt reconciliation earlier this year.
''I'm not going to start a tennis match with Simone, backwards and forwards, my statement that I released is 100 per cent truthful and accurate and I stand by that,'' he said.
''Simone knows the truth, that's the end of that one,'' Warne was quoted by Australian media.
