Los Angeles - Reunited and it feels so good for Britney Spears and her boys.

For the first time in nearly two months, the beleaguered pop star had face-to-face contact with sons Sean Preston and Jayden James, during a Saturday morning, court-monitored visit, sources confirm to E! News.

The boys, who have primarily resided at Federline's home in Tarzana since October, were packed into his gray Dodge Viper truck by a bodyguard and shuttled to Spears' home on the Studio City-Beverly Hills border around 9 a.m.

The visit lasted until noon, at which point the boys were driven back to Federline's, wearing smiles on their faces.

Aside from Spears and a court-appointed monitor, there were several other key personnel on hand, including: Britney's father, Jamie Spears; a Federline security guard; and a lawyer from the Luce Forward law firm, which is handling Britney's conservatorship for Jamie Spears.

According to an insider, the 26-year-old pop star was not permitted to take the boys, ages two and one, into another room without the others watching.

The ground rules for the visitation were hammered out Friday night, by lawyers for Luce Forward and ex-husband Kevin Federline.

"None of this would have happened if Jamie Spears had not been involved. That's for sure," Federline attorney Mark Vincent Kaplan told E! News Friday. "He gets a lot of credit for helping make this happen. But we've worked very hard with the conservator lawyers, as well, to make this all work."

Federline has had sole custody since October, and Spears hadn't seen Sean and Jayden since Jan. 3, after she refused to allow Federline's bodyguard to pick up the boys after one of her monitored visits and ended up under observation at Cedars-Sinai Medical Center.

The troubled songstress was stripped of her visitation privileges and has only been allowed to contact the boys by phone, but even those conversations have been few and far between, sources tell E! News.

Spears is not slated to see the boys tomorrow, according to a source, and plans to stay home and watch the Oscars in the company of her dad and Adnan Ghalib.
