OK! Exclusive: Jamie Lynn & Casey Together

In a rare public outing last weekend, a pregnant Jamie Lynn Spears walked hand-in-hand around her hometown of Kentwood, La., with Casey Aldridge, her boyfriend and father of her child.

"I love you babe,” the 16-year-old, who is now 20 weeks into her pregnancy, and beginning to show definite signs of a bump, professed openly to her beau after the two dined at one of their favorite local restaurants, Ambrosia's.

Despite false reports that the two had split, locals who have talked to the couple tell OK! that Jamie Lynn and Casey are "very much together and very much in love... They're adorable."
