Jamie Lynn Spears Makes First Appearance After Wedding

Just a few weeks after she tied the knot in New Orleans with her now hubby Jamie Watson, Jamie Lynn Spears is already getting back to work!

The 22-year-old flashed her diamond ring while performing aboard the USS Iowa in Los Angeles on Wednesday for the Go Country 105 concert.

Britney’s younger sis rocked black-on-black with a leather jacket, t-shirt and jeans, but gave the look a pop of color with some bright red pointed-toe heels.

She sang four sangs, including her single “How Could I Want More,” and even broke into the chorus of Brit’s “Oops I Did It Again!” (Wish I was there for that one!)

Jamie Lynn is currently preparing to release her debut country album.
