Secret cocktail James Bond and Jackie Kennedy reportedly enjoyed

It's summertime, which means it is time to kick back and enjoy a lovely, refreshing cocktail.

If you've ever wanted to channel Jackie Kennedy as a lady or you had dreams of having the panache and sophistication of James Bond, it won't be too difficult this summer -- all you need to do is whip up a drink with their favorite ingredient: Lillet.

Former first lady Jackie Kennedy was reportedly a huge fan of the Aperitif whether she was sipping or entertaining, and it's easy to see why. The aperitif was created in France in 1862 and was a popular drink in the 20s and 30s for special occasions. Later, it became a major hit post-WW2 in the U.S. and was very trendy among a fancier set. If you want to drink like Jackie, we'd recommend whipping up the Lillet Spritz this summer, which is light and refreshing.

Lillet Spritz

2 parts Lillet Blanc/Rosé

4 parts tonic water

Garnish with cucumber, mint and strawberry

Jackie wasn't the only fan of Lillet either. The aperitif, which now comes in three different expressions now, Lillet Rose, Lillet Blanc and Lillet Rouge, was also beloved by James Bond. The British super spy likes to sip on the Vesper Martini, which features Lillet Blanc. The cocktail is featured in Ian Fleming's first Bond novel, "Casino Royale" and it is named after Vesper Lynd, the original Bond girl, and one of the only women he ever loved. According to Fleming, the Vesper is "strong and cold and very well-made"— which definitely evokes the aura of 007 himself. Want to party like Bond all summer? Try the recipe below!
