Teaming up for a long day on the Los Angeles set of The Runaways, Twilight star Kristen Stewart and Dakota Fanning got their rock'n roll attitude going with some rough and tough action, according to celebbuzz.com.  But besides a regular day of shooting there are hot new pics of the pair playing Joan Jett and Cherie Currie.

The two got silly when Fanning, 15, fell over a trash can and she and Stewart, 19, had a big laugh before jumping on a car and kicking over a trash can.

Meanwhile, the day's fun-filled filming session comes on the heels of recent alleged reports that Kristen endured a minor tearful breakdown courtesy of  Joan Jett, who supposedly
A source recently told the New York Daily News, "Joan just wants Kristen to play an authentic version of herself, so she needled her a little bit too much. But she apologized when she realized how upset Kristen got."

In the highly publicized biopic about Joan Jett and her bandmates, Kristen plays the lead character while her 15-year-old co-star took on the role of the all-female band's lead vocalist, Cherie Currie.

Adding a little spice to the action, the much anticipated The Runaways is even more intriguing now that Stewart and Fanning are confirmed to share a love scene which as has been described as  "an intense lip-lock and their clothes end up scattered all over their hotel-room floor."

The Runaways is slated for a 2010 release.
