Even though Megan declared herself to be single a mere two weeks ago and was rumored to be having a romance with her Transformers: Revenge of the Fallen costar/Hollywood hottie Shia LaBeouf, it turns out that Fox is still smitten with Brian Austin Green.

OK! Magazine reports that Fox planned a double date with her sister, her sister's boyfriend and Green in Las Vegas for Saturday night.

Megan planned to arrive in Sin City solo that afternoon but missed her flight. However, Fox made the drive from Los Angeles with the trio, arriving at the Palazzo at approximately 3 in the morning.

And once there, she didn't waste any time in displaying just how much she still cares for the Notorious BAG.

“Megan and Brian are definitely together. They call each other baby and are just so cute together. I don’t think they ever really broke up," a witness tells the magazine. "They’re so comfortable and ridiculously cute. In the elevator Megan put on chapstick with her finger and then put the rest from her finger on his lips. They seem so happy together and so in love.”

Megan always has interesting ways of doing things including how she chooses to show her affection towards Brian!

It's just a shame that she can't put that much effort into showing her appreciation to  certain determined fans of hers.
