Rachel McAdams is dating Josh Lucas.

The 'Wedding Crashers' actress has moved on from former beau Ryan Gosling - with who she had a lengthy on-off relationship after they fell in love on the set of 2004 movie 'The Notebook' - and into the arms of notorious ladies' man Josh.

The new couple were spotted canoodling at the Purple Ball, which was held to celebrate US President Barack Obama's inauguration, on Tuesday, and left onlookers in no doubt they are an item.

A source told the New York Daily News newspaper: "They were so lovey-dovey. They were nibbling on each other's necks, gazing into each other's eyes and doing a lot of flirty touching."

Josh, 37, has previously dated Salma Hayek, Heather Graham and Anne Hathaway.

Rachel, 30, and Ryan, 28, split last April after dating for two years, but found it difficult to go their separate ways.

The sparked rumours they had rekindled their romance in July when they were seen getting close at Ryan's debut DJ set in Los Angeles.

In August, they were said to be "definitely together again" and even went on holiday to Toronto together.

However, in December it was announced they had decided to be friends rather than lovers.
