Britney Spears Jet Skis in Miami with Boyfriend Sam Asghari

Britney Spears seems to be getting back to her normal life one couple's activity at a time -- this time she's jet skiing in Florida ... but not without some advanced planning on the part of her father/conservator.

The singer was down in Miami this weekend alongside her boyfriend, Sam Asghari, as the two of them mounted some WaveRunners and hit the water with a splash. She was riding solo, and seemed to be enjoying herself as she caught some speed.

Britney's been going out a lot more lately with Sam -- whether it's hitting the town on a date near Thousand Oaks or going for a bike ride with the dude ... she's very visible.

What's even more intriguing about her cross-country trip here is that her father and primary conservator, Jamie Spears, filed court docs last month seeking to extend the conservatorship to include 3 other states outside of Cali ... and Florida's one of them.

At the time, we were told Jamie knew the Sunshine State is one of the places Brit likes visiting, so he preemptively sought to get a handle on things amid all the #FreeBritney drama from last month ... which appears to have simmered down since her court appearance.
