OK! Magazine has launched legal action against Heat Magazine for stealing their “world exclusive” on Britney Spears’ prego teen sister. The mag is being sued for publishing the OK! interview with sixteen-year-old Jamie Lynn Spears and claiming it as their own.

OK! Group Editorial Director Paul Ashford says: “OK! Magazine has established its reputation in the UK, the USA and throughout the world by the relationship of trust it builds with celebrities.”

“We go to all possible lengths within the law to protect these exclusives and safeguard the interests of the celebrities and of our own readers.”
