JEN GETTING CLOSE WITH LENNY KRAVITZ!

FRIENDS OF THE PAIR RECKON IT’S TIME THEY GIVE THINGS A PROPER GO

Jennifer Aniston’s friendship with rocker Lenny Kravitz has become the talk of Hollywood, as friends exclusively tell New Idea the longtime pals are taking their relationship up a notch!

The 52-year-old actress has been friends with Lenny, 57, for years. The superstars even appeared on Jimmy Fallon’s The Tonight Show together in 2013, where they teamed up for a game of Pictionary on the show.

The following year, Jen asked Lenny, who launched his design business in 2003, to work on the interior of her Bel Air mansion – and they have kept in touch ever since.

Now, sources say Jen and Lenny are “wearing down their phone charges” in a string of “late-night calls” that suggest a romance might be on the horizon.

“You could definitely describe the calls as flirty,” reveals our insider, who says Lenny’s been “giving Jen butterflies” since they met.

Back then, Jen was moving forward in her relationship with Justin Theroux. But that’s not to say the sparks didn’t fly.
