The `Great Gatsby` actor`s relationship with Victoria`s Secret model Erin Heatherton - which only began in December - has reportedly gotten so serious that he couldn`t wait for Erin to meet his mum Irmelin over the festive period.

A source who saw the threesome enjoying a brunch at the Four Seasons Hotel in Los Angeles on New Year`s Day (01.01.12) told the New York Post`s Page Six: "The meeting went well and mom and Erin were seen laughing. Leo and Erin seemed really happy."

Before getting serious with Erin, Leonardo was linked to a bevy of beauties following his split from `Gossip Girl` actress Blake Lively - who he had been in a relationship with for five months.

As well as seeing `Australia`s Next Top Model` contestant Alyce Crawford, Leonardo is also said to have been working his charms on 20-year-old catwalk beauty Kendal Schuler - who recently separated from Australian `Celebrity Apprentice` contestant Didier Cohen.

A friend of Kendal said: "Leo has told her she can visit any time she likes as long as she keeps it low key. She has taken him up on that opportunity already a couple of times.

"But she isn`t silly - she knows this isn`t serious and she is just enjoying the time with him."
