Her social media activity comes after her ex-husband Jason Alexander pleaded not guilty after he was accused of trying to “gatecrash” the pop star’s wedding last month.
The 41-year-old, who live-streamed the incident where he allegedly entered Spears’ wedding venue, was arraigned at Ventura County Superior Court earlier this month.
Alexander – who was married to the singer for 55 hours in 2004 – had been charged with stalking as well as four misdemeanors that included battery, trespassing, and vandalism.
Speaking to Page Six, Ventura County Senior Deputy District Attorney Erin Meister confirmed this week that Alexander entered a not guilty plea on all counts.
He appeared at the arraignment hearing from jail via Zoom. His next hearing is reportedly scheduled to take place on August 2.
Alexander currently remains in jail, with bail set at $100,00 (£84,500).
