Some of Hollywood’s hottest stars are being spotted all over Columbia, S.C. as filming on the movie Nailedcontinues in the capital city this week.

Oscar winner Reese Witherspoon and her boyfriend Jake Gyllenhaal were spotted making out just outside of the S.C. Governor’s Office this afternoon.

Apparently, the pair were coming back from a Starbucks in the city’s Vista District, where they have been seen together on numerous occasions since the movie started filming on the State House grounds two weeks ago.

Sources tell us Gyllenhaal has also accepted an invitation from S.C. Governor Mark Sanford to join him and his family for dinner tomorrow night at the Governor’s Mansion, although actress Jessica Biel has yet to accept the governor’s invite.

Reese Witherspoon hold hands and shares a laugh with boyfriend Jake Gyllenhaal on the set of his new movie, Nailed, in Columbia, SC, on Friday.

Reese, 31, and Jake, 27, playfully teased each other as they strolled along. Gyllenspoon look cuter than ever!

Nailed is an original romantic comedy about a naïve small town waitress (Jessica Biel) who accidentally gets a nail buried in her head, causing erratic and outrageous behavior that leads her to Washington DC. There she falls for a dashing, but clueless, Congressman who searches for the courage to save her.
