Jennifer Garner and Bradley Cooper spark romance rumors after the famous friends have a flirty beach day in Malibu.

Jennifer and Bradley appeared cozy enjoying a summer day sitting on the sand while his daughter Lea de Seine Shayk Cooper was making sandcastles as they lounged beachside.

The former co-stars have been good friends since appearing in the long-running sitcom Alias from 2001 to 2006 where they play best friends, Will Tippin and Sydney Bristow.

Cooper, 45, wore a pair of red swim shorts with his hair up in a man bun while Garner, 48, wore a navy cardigan, printed blue skirt, and sneakers for their excursion.

I must ask you to pardon my quarantine brain and weird space buns. Otherwise, let’s make @cooksillustrated Orange-Almond Biscotti. . From “The Best Recipe” Cookbook Ingredients: 2 cups AP flour 1 tsp baking powder 1/4 tsp salt 4 Tbsp unsalted butter, softened 1 cup sugar 2 eggs 1/2 tsp vanilla 1/4 tsp almond extract 3/4 cup whole almonds, toasted and chopped coarse 2 Tbsp minced zest from an orange . Directions: 1. Adjust oven rack to middle position and heat to 350°. Whisk flour, baking powder, and salt together in medium bowl; set aside. 2. Cream butter and sugar together until smooth, about 2 mins with mixer at medium speed. Beat in eggs one at a time, then extracts. Stir in toasted and chopped almonds and zest. Sprinkle dry ingredients over egg mixture, then fold in until dough is just mixed. 3. Halve dough and turn each portion onto an oiled cookie sheet covered with parchment. Using floured hands, quickly stretch each portion of dough in a rough 13×2 inch log, placing them about 3 inches apart on the cookie sheet. Pat each dough shape to smooth it. Bake, turning pan once, until loaves are golden and just beginning to crack on top, about 35 mins. 4. Cool the loaves for 10 mins; lower oven to 325°. Cut each loaf diagonally into 3/8 inch slices with a serrated knife (normal-ish cookie size). Lay the slices flat, about 2/3 inch apart, on the cookie sheet and return them to oven. Bake, turning over each cookie halfway through baking, until crisp and golden brown on both sides, about 15 mins. Transfer biscotti to wire rack and cool completely. 5. Yum.

Jennifer gushed about Bradley in 2018 promoting her HBO show Camping calling him ‘so cute’ and bragging about his ‘blonde-tipped hair’. In the same Entertainment Tonight interview, she exclaimed, ‘look, he can really sell something. Bradley Cooper, what a sweetie’.

The outing comes on the heels of Garner separating from her CEO boyfriend John Miller after dating him for about two years before calling it quits. This marked the first serious relationship for the Peppermint star since splitting from husband Ben Affleck in 2005.

The Guardians of the Galaxy vol. 3 actor has not romantically linked since his split from his model girlfriend and has focused his efforts on being a doting dad to his 3-year-old daughter.
