We were wondering why Britney Spears's bodyguard rushed back to her house while our girl was shooting!

He returned to Brit's Summit home to pick up mom Lynne and bring her back to the studio to visit Britney on the set. They should be arriving in Brit's black Escalade any minute!

So nice of Lynne to support her daughter while she films - hope it's going well!

UPDATE - Lynne still hasn't arrived at the studio - looks like she's stopped to shop first!

Stay tuned for more updates!
