LOS ANGELES, California (X17online) - Britney Spears was reunited with her sons, Sean Preston, 2, and Jayden James, 1, on Mother's Day, just days after a Los Angeles County court granted her extended visitation rights.

Spears' boys arrived at her Beverly Hills home around 9 AM on Sunday, and Spear's father Jamie was spotted taking the boys for a ride in their favorite wagon and snapping pictures of his daughter and his grandsons. The boys left around 6:30 PM, and afterward, the mother-of-two took her mother Lynne to the trendy southern European eatery Sur in Beverly Hills where she dined twice last week.

Meanwhile, Spears' pregnant 16 year-old sister Jamie Lynn was in the family's hometown of Kentwood, Louisiana on Mother's Day and X17 spotted the younger Spears with her boyfriend and the father of her baby, Casey Aldridge, attending a local church.

Spears has been spending time with her mother, from whom she was recently estranged; the two flew back from Kentwood together last Sunday (May 4) after attending sister Jamie Lynn's baby shower. Spears and her mother were out this Saturday (May 10) morning when Spears treated her mom to a coffee from Starbucks to kick off her Mother's Day weekend.

On Sunday, while both her boys were present, X17online snapped some exclusive pictures of Britney smoking outside her house. These and the other X17 images of Spears' suspiciously growing belly have led to speculation that the singer could be pregnant and magazine editors from around the world have been contacting X17 asking if she is, in fact, expecting her third child.
