Doctors, dancing, a shockingly bad duet and the demise of a dysfunctional romance? Seems it was a busy weekend for Britney Spears. Here's the latest:

Britney and Adnan in Los Angeles on Jan. 22

Is the currently line-toeing cautionary tale on the outs with her still-married paparazzo beau, Adnan Ghalib? So claims the London Sun, which says a suspicious Brit went all Columbo on the facial hair-foolhardy photog and checked the text messages on his iPhone.

"There were about a dozen from one girl, all sent on one day," alleges a source to the tab. "They were pretty saucy stuff with sexual references -- certainly not the sort you'd send to just a friend. Britney lost it and started yelling."

According to the snitch, "She was demanding to know who sent the texts and shouting, 'What's this about? You're cheating on me.' Adnan said the girl was just a friend, but Britney got more and more angry. Then she told him, 'That's it. It's over.'"

Spears supposedly emphasized her split decision by chucking his phone into the pool.

And while the London Daily Mail says Ghalib was seen Sunday in the company of a dewy waitress-cum-would-be-model, the Sun believes he's trying his darnedest to win his meal ticket Brit back with floral mea culpas.

One missive accompanying a bouquet purportedly read, "Bebe, I really miss you lots and lots and lots. Can't wait til you come home to a milky bowl of soup. Love you always. Adnan."

You know, we're just gonna ignore the ickiness potential of that "milky bowl of soup" phrase and move right along to the house call Spears received on Saturday.

TMZ.com reports her driver swung by UCLA Medical Center and picked up her psychiatrist and a court-appointed physician for a scheduled visit at her Beverly Hills, Calif., home.

This is said to be a positive sign that Spears is making an effort to follow the tough love rules laid out in the post-conservatorship world (she's already earned back monitored visitation with tots Sean Preston, 2, and Jayden, 1, who spent Monday morning with her).

Following the medical visit, Britney headed over to the Millennium dance studio, where she once again taught a class of impressionable young girls, reports OK!.

One song the tykes probably weren't shimmying to is "Dramatic," a brain-numbingly appalling ditty featuring a breathless Spears squeaking out lyrics such as, "Now there's another ringing my bell-a, under his spell," alongside shameless, stop-at-nothing fame craver Heidi Montag.

Why would Britney stoop to sing with the scheming, Z-list squeeze of Spencer Pratt, whose previous musical offering, the helium horror that is "Higher," should be classified as a form of torture? Perhaps she didn't.

"It's not authorized and it wasn't set up in any way and they never spent any time together in the studio," a source at Spears' record label explains to Us. "This was never a planned song or duet in any way."

Adds a mole to Perez Hilton, "Heidi and Spencer got their hands on an old demo recording of Britney's that never made it onto any of her albums. They've been working with a lot of producers on Heidi's new album and one of them gave them the track. They decided to turn it into a duet instead of having Heidi re-record the song with just her vocals because they knew they'd get more press this way."
