|Bradley Cooper and Scarlett Johansson|
The 27-year-old actress - who was previously married to Ryan Reynolds - and her 'He's Just Not That Into You' co-star appeared "wrapped up in each other" as they flirted and laughed through a meal at Wolfgang Puck's restaurant at the Bel Air Hotel in California on June 11.
A source told RadarOnline.com: "They seemed very comfortable together and it was pretty obvious they are into each other. Bradley seemed almost distracted by Scarlett's beauty, especially since she was wearing a very low cut dress, and Scarlett was totally working her charms. She kept flipping her hair when she laughed at his jokes.
"The chemistry between them was very evident and they looked totally wrapped up in each other - very cute! They were definitely having more than a 'friends' dinner, it seemed pretty obvious they totally have the hots for each other."
According to onlookers, Bradley - who has previously dated actresses Renee Zellweger and Zoe Saldana - picked up the bill for the meal and the pair then relocated to the venue's piano bar to continue their evening over drinks.
