Gomez laughing at 'weird boy' Bieber

Selena Gomez is amused by Justin Bieber's recent bad behaviour.

The 20-year-old 'Who Say's singer - who dumped the 19-year-old Canadian star in January after two tumultuous years together - has reportedly been laughing at his immature actions which included arriving two hours late to a concert and threatening a photographer in London earlier this week.
