The now-vanished footage shows the 38-year-old getting ready for the Logies, when Rebecca walks in.
The clearly surprised performer pulls a shocked face.
"Always before dressing, during shower," his model girlfriend captioned the Instagram Story.

Lee then went on to post the video on his account with the caption, "Extreme invasion of privacy."
He then filmed his own video stressing the importance of grooming.
"Shave everything, don't risk embarrassment," he captioned the video.
"It's the Logies, you gotta shave your whole face," Lee explained in the video. "You can't risk having an errant hair that a glossy mag picks up on, so that's all I can do."
The duo looked dashing as they hit the red carpet, with Rebecca sporting an Elliot Garnaut floor-length, feathered dress with thigh-high split.
