Britney Spears is so protective over her baby son Sean Preston, she will only let her own mother LYNNE hold him.

Lynne joined her daughters, JAMIE LYNN, Britney and son-in-law Kevin Federline at the launch of Britney's father JAMIE's poker computer programme in Las Vegas, Nevada, over the weekend (07-08JAN06).

Lynne, 50, says, "She's really picky. She's doesn't let just anybody hold Sean, but she lets me."

The matriarch also lashed out at reports Britney and Federline's marriage was on the rocks, saying, "She's very happy. Kevin does change diapers. I'm very close to him."

Britney adds, "He's (Sean) so happy. He laughs all the time."
