Hilary Duff has confirmed she has got back together with her ex Matthew Koma.

The couple split in March but were romantically linked once again after they were spotted smooching, and she has admitted they are an item again for the third time.

She said: ''It's going so great.''

Hilary also compared her reconciliation to Selena Gomez and Justin Bieber's on/off relationship, admitting ''timing'' plays a big part in a relationship.

Speaking on 'The Talk', she said: ''I mean, this is like the third time that we've dated and I think that what [Selena] says has so much merit to it. Timing is such a big deal ... third time's a charm.

''I think that you have history and a past with someone and love, and just because it doesn't work out the first time, the second time, as long as there's not too much damage done, then, it can always work out again.''

The 30-year-old actress was previously married to NHL player MIKE COMRIE, who she tied the knot with in 2010 but she filed for divorce in February 2015, citing irreconcilable differences, and it was completed a year later.

The 'Lizzie McGuire' star shares five-year-old son Luca with Mike, and has previously admitted she felt ''pigeonholed'' for becoming a mother aged 24.

She said: ''I feel like I was judged for having a baby too soon, and getting married too soon and now, I'm pigeonholed for being a 'mom'.

''Lots of women in the industry that don't have a child yet are judged.

''We are the most in demand and the most desirable, but the most judged and the hardest on one another. It's so much scrutiny.''
