Justin Bieber has demanded his former neighbours undergo a mental evaluation after they claimed living next door to him is wreaking havoc for their emotional and physical well-being.

The Sorry hitmaker was found guilty of vandalism in 2014 after pelting Jeffrey and Suzanne Schwartz' home with eggs but, despite finishing his probation period for the charge last month, he's now tied up in another legal battle with the pair.

According to gossip website TMZ, the 22-year-old singer and his lawyers have called on the couple to undergo a test to prove they're battling psychological issues as a result of the infamous egging debacle two years on from the incident.

Jeffrey and Suzanne - who claimed in their previous lawsuit Justin had subjected them to the consequences of loud parties and drug use - have claimed they're still battling with headaches and insomnia following the infamous incident, despite the pop star moving out of the exclusive gated Calabasas community in California last year.

Meanwhile, it was claimed Justin finished his probation early last month, 30 days earlier than scheduled.

He received the punishment two years ago after he pleaded no contest to misdemeanour vandalism.

He was also told to carry out five days of community service at a homeless shelter and fork out an estimated US $80,000 in damages to his neighbours.

He was also ordered to undergo anger management counselling.
