Simone Callahan lover not "pressured" by Shane Warne, Liz Hurley

Shane Warne and Liz Hurley's recent engagement has reportedly not bothered his ex-wife Simone Callahan.

The Australian cricketer is though to have split from Callahan around the time he was first linked to Hurley, but her new boyfriend Toby Roberts said that the former couple have a great relationship and that Warne's upcoming wedding will not affect his romance with the mother of three.

Roberts, who has been dating Callahan for about nine months, told The Daily Telegraph: "[Shane and Simone have] a very amicable, mature relationship which is very healthy. There is obviously water under the bridge, but you get that with every relationship. Their main concern is the kids."

He also revealed that he feels "absolutely no pressure" to propose to Callahan after Warne and Hurley's whirlwind romance.

Callahan and Roberts apparently signed a lucrative deal with a magazine to tell all about their relationship only a few days after Warne and Hurley's engagement was announced.

Early on in their relationship, Callahan and Roberts were spotted getting "pretty hot and heavy" in Sydney. A friend of hers said at the time: "Simone is in a good place - very happy - and she so deserves this. Simone's an amazing mother and a really great person and it is just wonderful to see her so happy right now."
