As the worlds press speculates about the nature of their relationship, Lindsay Lohan and Samantha Ronson are going about their business.

Sam continues to enhance her reputation as a top DJ on the celeb party circuit and Lindsay has put the finishing touches on her 3rd studio album – ‘Spirit In The Dark’.

So it’s not surprising then that Ms Ronson previewed a couple of tracks from the album – which features Pharrell, Snoop and Akon – at her latest gig in Las Vegas.

The lucky partygoers to hear the new LiLo material – including Shannon Elizabeth, Billy Zane and Tyrese - were at an exclusive Fourth of July bash at TAO Beach in the grounds of the Venetian hotel and casino.

As well as the new tunes, the high rollers were enjoying TAO’s premium cabanas complete with Xbox, bar and flat screen TV’s.

If the report that Britney Spears may be the new face of Bally Total Fitness turns out to be true, she could be back in shape — back in the studio and back onstage — sooner than you think.

Seems Brit’s parental units have been talking to Bally about an endorsement deal. And surprise, Larry Rudolph is also involved.

Britney has been hitting one of their L.A. health clubs daily, doing lots of personal training and working with their nutritionist. No more late-night, junk-food-junkie joy rides!

Did I mention she’s reportedly working out for free right now? A Bally insider told TMZ, “We’re more interested in Britney Spears’ health than her $19.”

A Los Angeles County Superior Court commissioner ruled Wednesday that Britney Spears’ father would retain control of his daughter’s finances and estate for five more months.

Superior Court Commissioner Reva Goetz extended James Spears’ control until July 31, said court spokesman Alan Parachini. Parachini wasn’t immediately able to provide more information.

Spears was named co-conservator of the pop star’s estate after she was hospitalized twice in January. His temporary authority was to continue until Monday.

the year leading up to the hospitalizations, Spears had been caught on camera by paparazzi engaging in increasingly bizarre behavior. She shaved her head, beat a vehicle with an umbrella, wore skirts sans underwear and left her car on a busy street with a flat tire.

The court commissioner handling Britney Spears’ custody case has repeatedly ordered the pop star to undergo a psychological evaluation, but she has refused to comply, TMZ.com reported.

Commissioner Scott Gordon has issued multiple orders — known as a 730 evaluation, TMZ said.

Meanwhile, Spears’ lawyers will go to court Wednesday at 11:30 a.m. ET and ask Gordon to allow the singer “monitored visitation” with her two sons “in a therapeutic setting,” TMZ reported.

But TMZ is hearing buzz that Spears’ ex-husband Kevin Federline (and probably the court) will not want Britney to bypass the 730 evaluation process. That could make it unlikely for Brit’s lawyers to win a bid to regain visitation in a therapeutic setting, the Web site said.

On Monday, Spears left the deposition in her custody battle nearly two-and-a-half hours after arriving at the offices of Federline’s attorney Mark Vincent Kaplan, People.com and TMZ reported.

Spears’ deposition has been an emotionally difficult experience that has only just begun, Kaplan told People magazine.

“We are going over things that are very, very gut-wrenching,” Kaplan said Monday night, speaking outside of Katsuya restaurant in Brentwood. He declined to discuss specifics of the questioning, but said, “Just to revisit them even in your own mind would not be pleasurable.”

“It’s not something anyone would enjoy,” he said.

Spears was about 50 minutes late for Monday’s deposition.

“After an hour I would have been over it. I was prepared to terminate had she not showed at that time,” he told People.

Kaplan said there will further depositions in the unspecified future, claiming that he has only worked through “2 percent” of his questions. But he added that he was heartened by the idea of even having the meeting in the first place.

“She came for her deposition, that’s great,” Kaplan said.

In an interview with TMZ, Spears’ attorneys Sorrell Trope and Tara Scott said the singer was “in good spirits” at Monday’s deposition.

Spears, 26, and Federline, 29, have been wrangling over custody of their sons, 2-year-old Sean Preston and 1-year-old Jayden James.

Federline has temporary custody of the children because Spears has defied court orders. The two were married in October 2004 and divorced in July. Spears also does not have visitation rights at this time.
