Jamie Lynn SpearsJamie Lynn Spears has seemingly confirmed the rumours that she’s engaged to marry boyfriend Casey Aldridge.

The currently pregnant 16 year old is said to have shown off her new engagement ring to friends earlier in the week after Casey proposed over Easter weekend and yesterday the Zoey 101 star was seen wearing the rock - and a t-shirt proclaiming in large text across the front: “The Rumors Are True”.

Jamie Lynn was spotted at Babies ‘R’ Us in Baton Rouge, around 80 miles from her Kentwood, Louisiana home, with a female friend yesterday and the pair are said to have spent around two hours putting together a list for her forthcoming baby shower.

An onlooker reports: “She was looking at a range of items, from cheap romper suits to top of the line items, but they were overwhelmingly blue.”

Jamie Lynn, the younger sister of Britney Spears, is expected to give birth around May.
