Old habits die hard.

As the Trump family was introduced at the Inauguration swearing in ceremony on Friday, cameras caught Bill Clinton eyeing Ivanka Trump as she was making her way to her seat.

Cameras captured the former president staring across the aisle as Trump’s children were introduced.

Moments later, Hillary turns around catches him in the act and glares at Bill. He shoots her a quick glace and she looks away, appearing incensed.

Bill Clinton also appeared to be in a daze at times.

He repeatedly stood with his mouth agape and couple be seen chewing on his tongue.
