London, June 7 (Inditop) Michael Jackson, who hasn’t been seen without a veil in the recent past, let his guard down to allow the world a rare glimpse of him and his kids.

Prince Michael I, 12, and Paris, 11, were seen without their customary masks on Thursday, reports thesun.co.uk. They were spotted as they joined their father at a Los Angeles recording studio without any veil.

But when they left the premises two hours later, they were wearing their masks again.

Jacko, 50, was preparing at London’s O2 Arena for his 50-date residency event, which kicks off July 13.
