Jessica Biel paid fiancé Justin Timberlake a visit in Atlanta – his temporary home while he's filming Trouble with the Curve – and the two have been spotted all over town getting affectionate.

During one recent outing, the two were strolling around Piedmont Park before joining four other friends for a casual late lunch at Tex-Mex hotspot Tin Lizzy's. Timberlake opted for the restaurant's signature "Southern Comfort" taco with chicken, goat cheese, fried pickles and BBQ sauce.

"They were chill but acting affectionately," Atlanta resident, and fellow diner, Deanna Whidby tells us. "Jessica was rubbing Justin's back."

A source at the restaurant adds that Timberlake was very gracious with the staff and Biel was happy to flash her engagement ring while the group enjoyed live music on the patio. – Jennifer Bradley Franklin
