Britney Spears is reportedly on a mission to win back her kids full-time.

Insiders are citing the singer’s renewed determination to be reunited with her two boys, Sean Preston, 2, and Jayden James, 1, as a major factor behind her noticeably less manic lifestyle in recent months.

“Britney wants her kids back,” one insider reveals to OK!. “And she will do everything in her power to make that goal a reality.”

Even her ex-husband Kevin Federline’s attorney, Mark Vincent Kaplan, concedes that Britney has come along way since the hostage standoff on January 3, after which she lost all visitation rights.

“Britney’s progress over the last two months is good,” he tells OK!. “No surprises, nothing to be alarmed about, and that’s all very positive.

Britney’s camp will once again go before Los Angeles County Superior Court Commissioner Scott Gordon on May 6 to ask for overnight visits with her sons.

If successful, she will be one step closer to regaining the 50/50 custody-split as laid out in the terms of her divorce.

Keep up the good work, Britney!
