Britney Spears is on the move after splashing out on an extravagant home which is costing her $25,000 a month to lease.

The pop princess is relocating with her boyfriend, Jason Trawick and sons Preston, 6 and Jayden, 5, and there will be plenty of room for the growing boys to play.  The 10,000 square foot mansion sits on almost two gated and fenced acres.

The luxury pad, just outside of Los Angeles, boasts an infinity pool, private gym, a home theater and even its own pub!

It's just a few miles from Brit's current home in Calabasas, which she has been leasing since January, 2009.

Spears will be settling back into SoCal for the first time in six months when she returns from her world tour, which came to an need in San Juan, Puerto Rico on Saturday night.

As RadarOnline.com reported, the singer's family came out in force to support her as she waved goodbye to her Femme Fatale tour.

Her boyfriend Jason, mom Lynn, both her sons, sister Jamie Lynn and niece Maddie all came on stage as she took her final bow.

When Spears returns to Los Angeles this week, she'll be preparing for the move to the new home and also deal with some pending legal business.

She is no doubt hoping her conservatorship will be lifted during a hearing on December 14, and then perhaps there will finally be a wedding to plan for her and Trawick.

She's been around the world and back since her Femme Fatale tour began last June, and Saturday night it came to an end in San Juan, Puerto Rico.

Britney Spears celebrated by bringing her pal Pauly D back for one more performance, and giving him her trademark lap dance midway through the show.  Several male members of the audience got called up on stage for the same treat.

Brit's family was there in force too.  Her sons Preston and Jayden, boyfriend Jason Trawick, and sister Jamie Lynn with her daughter Maddie, all surrounded her for a final bow.

Her dancers celebrated by covering Spears with silly string.

The tour grossed hundreds of millions of dollars, was sold out in every city, and was even warmly received by most critics.

Now it's back to L.A. for Spears --  who turned 30 earlier this month -- and some legal business.

She has a scheduled conservatorship hearing on December 14.  It's likely the conservatorship will finally be lifted, paving the way for Brit and Trawick's wedding.

Dad K-Fed is a team's coaches and proudly cheered his son on while wearing shirt and hat matching Preston.

In the stands -- and right behind home base -- was Preston's equally proud mom who was joined by her younger son Jayden and her talent talent boyfriend Jason Trawick.

Trawick seemed especially close to Jayden. The four-year-old sat in his lap while the game was on and left the field holding Jason's hand.
