While “Melrose Place” is hot and steamy between Ashlee Simpson-Wentz and Colin Egglesfield during filming, recent reports tell that real life is getting more intimate between the two, also.

Tabloid fodder tells that, in between filming, Ashlee was flirting with Colin while husband Pete Wentz was on tour.

While playing a scandalous Violet Foster, Ashlee was dressed only in a robe and kept grabbing Colin’s hand and hugging him. An insider tells Star magazine, “They hung out together for hours. She giggled nonstop and did the whole hair-flip thing.”

Ashlee has always thought Colin, who plays Auggie Kickpatrick, was attractive and a friend says, “One of the first things Ash said was, ‘The guy who plays Auggie is really hot.”

But while Ashlee has her fun, husband Pete is jealous. The two have been fighting at their top over him and it’s even said to be starting to affect her work.

Sources tell that, on the set, she has even broken down in sobs after angry phone calls.
