Prince William and Kate Middleton have slipped into a routine in the week after their lavish wedding.

William returned to work in north Wales as a helicopter rescue pilot for the military and has participated in two rescue operations since coming back, the British military said Thursday.

The couple decided against an immediate overseas honeymoon after getting married in London at Westminster Abbey on April 29. They opted instead to spend last weekend in Britain before William returned to military duty.

William was among a four-man crew operating a Royal Air Force Sea King helicopter, which airlifted a 70-year-old man with a suspected heart problem to a hospital Wednesday, the military said. Later, the helicopter rescued four hikers after one of them experienced vertigo.

Middleton, now known as the Duchess of Cambridge, has been out doing the couple's errands. Front page photographs due to be published in British tabloids Friday showed Middleton pushing a shopping cart at an upscale grocery store in Anglesey, where the pair have their home.

The images _ released late Thursday _ show Middleton wearing a thin white V-neck sweat shirt under a green knitted throw. Her sapphire engagement ring peeked out over the cart's handlebar as she skipped across the store's parking lot. The Daily Mail reported that she was wearing her gold wedding band under her engagement ring.

"Kate's Back up Aisle," joked The Star newspaper.
