In good shape: Britney's mother Lynne Spears looked in great shape as she played with her grandchildren in a hotel pool in Dallas
She may have three children and three grandchildren but one thing is for sure - Britney's mother Lynne Spears is looking in great shape for her 56 years.
The grandmother who has penned two books with her daughter showed off her fabulous figure in a black swimsuit as she played in the pool with her grandchildren.
Lynne was looking trim in the low cut one-piece as she enjoyed spending some quality time with the little ones in a Dallas hotel pool.
And Britney’s boys Sean Preston, five and Jayden James, four, seem to be having a great time as they pose up against the glass with Britney’s oldest proving quite the swimmer, posing open eyed underwater.
In her arms Lynne is carrying Jamie Lynn’s daughter, three-year old Maddie Briann Aldridge.
The Mississippi-born mother of two has been supporting her oldest daughter Britney on her Femme Fatale tour which will see the 29-year-old on 33-dates across America.
Reviews of the show have been hugely positive, and the star's decision to sing live has been particularly praised.
Britney and her mother haven’t always enjoyed such a close relationship.
Lynne has even written a book about bringing up children in the public eye entitled Through The Storm: A Real Story Of Fame And Family In A Tabloid World.
In the book, she describes her feelings at watching her daughter's public cries for help and her fight to remove Britney's so-called 'manager' Sam Lutfi from her life.
Recalling the night in February 2007 when Britney shaved her head, Lynne told Heat magazine: 'I knew she was hurting, but when I saw this happen, I was in shock. I didn't know what to do.’
Earlier this month it was revealed that Britney’s ex-husband Kevin's family are selling items from their wedding in a bid to cash in on the ill-fated romance.

Kevin Federline’s grandfather, Earl Story, has just put several items up for auction on eBay from K-Fed's glory days with the pop princess.
Among the items up for sale is the elegant invitation to the former couple's wedding, with bids starting at $1,000.
Also included is a hat that Kevin wore to an awards show with his then wife.
Cashing in: Kevin Federline's grandfather is selling items from Britney and Kevin's failed marriage on eBay
There is an invitation to one of Britney's baby showers and 14 wedding pictures, some of which are said to have never been seen before publicly.
Britney and Kevin were married in 2004, at a private residence in Studio City, California, after three months of dating.
The couple had two sons, and were divorced two years after they tied the knot.
A message posted on the eBay auction page says Kevin's grandfather is selling the items 'to help fund his retirement'.
