Jennifer Aniston and Justin Theroux Holding Hands Pictures

Jennifer Aniston held on tight to boyfriend Justin Theroux's hand as they stepped out after dinner at the Shoreditch House in London last night. Jennifer was sporting her second sexy black dress of the day after she wowed in a leather mini at her Horrible Bosses photo call in the morning. She changed it up for the red carpet premiere, where Jennifer joined her Horrible Bosses costars — including Charlie Day, who revealed that he just met the "very polite" Justin Theroux. This isn't Justin and Jennifer's first PDA moment, though it is a sign they're getting more comfortable bringing their relationship into the spotlight and the two look hot together in their matching date-night looks.
