Britney Spears and her agent/beau Jason Trawick announced their professional split last May, but now Brit and Jason are back on ... in every way! Mr. Trawick is Britney's agent once again, according to Us.

"Jason will be part of the team handling her career. He won’t be the only agent working with her, he will handling acting endeavors, but there will be a big music department also on her account," a source tells the mag.

The pop star has enjoyed several recent holidays with her 39-year-old William Morris Endeavor Entertainment agent, and despite Brit dropping his representation last year, they've remained romantically involved.

As for why they're back on professionally, the source adds, "Jason is someone the family trusts, they know he will make the best decisions for her and she feels comfortable with him. WME is absolutely the best choice for Britney. They are the best at what they do and her team recognize that."

Britney and Jason have been dating for two years.

All in a day's work!

The "Hold It Against Me" singer spent MLK Day out and about in Los Angeles. First, Britney Spears - along with beau Jason Trawick - stopped by Conway Recording Studios and later at Rite Aid in Calabasas.

First of all, Brit's hair extensions are looking a lot better! And second, we can't wait to hear more new music from the pop princess. Hurry up with that album, girl!

Britney Spears and Jason Trawick left her agent boyfriend's office at William Morris Endeavor Entertainment TOGETHER in Brit's white Mercedes G-Wagon just moments ago. It appears the couple wants to show a united front as they face reports Jason abused Britney -- reports the couple's various reps and attorneys say are totally false.

It's been a wild ride for the pair today with voice recordings from Britney's ex-husband Jason Alexander talking to a woman who is reportedly the pop star about her boyfriends alleged abuse -- that boyfriend being Jason Trawick.

Brit's peeps came out swinging, calling the recordings "ridiculously" fake and labeling them as defamatory. But Jason Alexander defends his tapes (which he apparently sold to the tabloid), saying he's been friends with B since the two were kids and he knows her voice well. After all, they were married for 55 hours, right?!

But that doesn't satisfy Spears' legal team -- they say they're preparing a lawsuit at this very moment.

Britney went to visit Jason at his office today just after 3 pm, left less than an hour later and U-turned back to the office for a second visit around 4:15. She stayed for about 30 minutes and then she and Jason left together to head home to Calabasas.

What do YOU think -- victims of bad reporting or are Brit and Jason covering something up?

X17 photographers staked out outside the William Morris Endeavor agency in Beverly Hills where Jason Trawick works, tell us Britney left her boyfriend's office about 30 minutes ago, headed to the freeway to go home to Calabasas, but turned around when she got to the 405 and went BACK to Jason's office!

Brit's inside now, again, presumably having a pow wow with her agency boyfriend JT. Are these two planning their legal battle against the tabloid that published audio recordings of a woman they claim to be Spears telling her ex-husband Jason Alexander her new man is hitting her? ... As a united front?

Or are these two duking it out, trying to figure out the next step in their relationship?

Stay tuned for photos coming soon ...

Who knew the pop princess adored Will Smith's daughter and her new single so much?

Decked out in casual sweats, 28-year-old Britney Spears - along with her boyfriend Jason Trawick - worked on their fitness together at a Beverly Hills gym yesterday afternoon...

Meanwhile, our girl Brit Tweeted "Have you guys seen Will Smith’s daughter @OfficialWillow’s video? SOOOO CUTE!!!!"

Guess that means Ms. Spears is a big fan of whipping her hair, too!

Yesterday we spotted Britney Spears' boyfriend Jason Trawick grabbing a to go bag from Willy's Smokehouse Bar & Grill in Los Angeles, and he looked absolutely thrilled to be playing delivery man for the day. Our photographers on the scene tell us Jason nearly caused an accident doing an illegal u-turn on the way home, but you know he was just trying to get back to his lady love as quickly as possible!

Just temporary ones though! Phew.

The legendary Ms. Britney Spears continued to beat the LA heat this weekend, throwing on a skin-tone tank top (with a flirty pink bra underneath), short shorts and wedges while buying some toys for her tots at Toys R Us in Calabasas on Saturday...

Boyfriend Jason Trawick, however, didn't keep as cool in t-shirt, jeans and shoes.

Regarding the tats - which appear to be a butterfly, flower and a fox - it's possible son Jayden is behind 'em! The youngster sported a tattoo of his own around his neck when we saw him and Brit at My Gym this past Thursday. (Take a look in our gallery for more pix!)

Sidebar, it looks like Brit and Jason's romance is as strong as ever! The Circus singer held tight onto her man throughout the shopping excursion:

And that's exactly what she and Jason Trawick were doing!

While on their romantic vacay in Maui, Britney Spears and her boyfriend took a break from shopping and smoking to spy on an actual wedding taking place at their hotel... aww! How sweet.

And what's going on in Brit's eyes in this pic below - she looks somewhat longing:

Does this mean Queen B wants another wedding for herself? A wedding that would feature Jason this time around???
