Jamie Lynn Spears house hunting with Casey Aldridge

Pregnant Jamie Lynn Spears has been house hunting with boyfriend Casey Aldridge.

The Zoey 101 star, 17, and her 18-year-old partner -- who are expecting their first child together this summer -- have reportedly made a $300,000 offer for a three-bedroom property in Mississippi.

A source said: "Jamie Lynn is really excited over having a home of her own."

The house, which is located on five acres of secluded woodland in the town of Liberty, boasts two bathrooms, marble floors and a game room.

Meanwhile, Beyonce Knowles' little sister Solange has offered Jamie Lynn advice on being a young mother.

Solange -- who gave birth to her three-year-old son Daniel when she was just 18 -- said: "You just have to make the best decisions for you. Who are we to say what's right and wrong for a person?

"I moved to the country for a year without any nannies or babysitters when Daniel was born.

"My son has been my focus ever since the day he was born. He's been the light of my life, the inspiration behind everything.

"I'm sure a lot of people perceived that I was going to be a young, irresponsible mom, but I think that there are some mums who are 35 who are just as irresponsible."
