Daddy-to-be Casey Aldridge has been close to the Spears family for some time, as both a hometown boy dating the youngest Spears daughter, and acting as a buffer between the teenage actress and the pressures of Hollywood.
"He took amazing care of Jamie Lynn," a source close to the Spears family tells People. "Anything ever went wrong, he always comforted her. He took care of her."
Jamie Lynn Spears and her mother, Lynne Spears, say that Casey Aldridge is the father of the baby the 16-year-old announced she is pregnant with.
Casey Aldridge is believed to be either 18 or 19 and has stayed out of the Hollywood spotlight, only occasionally accompanying Jamie Lynn to events.
He grew up in Liberty, Miss., about 30 miles from the Spears family home base in Kentwood, La., and played high school baseball and football (Aldridge is listed in a sports directory as a lean six-foot-one, and 165 pounds).
Recently, he has been living in Southern California and was a fixture at the condo where Jamie Lynn was staying while filming her Nickelodeon series Zoey 101.
Jamie Lynn Spears' parents love Casey Aldridge, even though he got her pregnant.
In California, Casey Aldridge drove her to the set every day and stayed while she worked, impressing both Lynne Spears and Jamie Lynn's father, Jaime Spears.
"Jaime always talks about how he really likes Casey because he's a great guy," the Spears family source says. "Lynne really likes him, too. He's a good kid, cares a lot about Jamie Lynn. They both adore Casey."
The pregnancy, a source close to Casey Aldridge says, was a surprise.
"I'm sure it was a shock to him," the source says. "He has all sorts of plans for his future. He wants to start his own business, maybe get a degree and make something of himself."
Casey Aldridge will also take responsibility for his actions.
"He's a stand-up guy, and he will take care of the baby," the source says. "He is not the type to let her deal with it on her own. He will be there in any way he can for Jamie Lynn... I know a baby wasn't in his plans for right now, but he'll do what he has to do, and he'll be a good father. He really will."
