Former 'Neighbours' star Erin McNaught splits from model Nathan Joliffe

Erin McNaught has reportedly split from boyfriend Nathan Joliffe.

The Australian television presenter and actress, who is best known for playing Sienna Cammeniti in Neighbours, was first linked to Australian Amazing Race winner and model Joliffe in 2009.

A friend of McNaught told the Herald Sun: "They were just heading in different directions [and] arguing a lot. It wasn't working so they went on a break for a bit but then decided to break up."

Joliffe has reportedly since changed his Facebook status to "single".

McNaught once described them as "two peas in a pod" and they moved into a Sydney apartment together earlier this year.

The former Miss Universe Australia used to date Roosters captain Braith Anasta, but they split shortly before she met Joliffe. Anasta is now engaged to ex-Home and Away actress Jodi Gordon.

Joliffe's fellow Amazing Race competitors Chris Pselletes and Anastasia Drimousis announced their split weeks after filming finished. Pselletes later admitted that he was "ashamed" at how badly he treated Drimousis during the show.
