'Clingy' Lena Dunham Won’t Stop Bothering Ex-Boyfriend Jack Antonoff

Maybe it’s time for a Girls intervention! RadarOnline.com can exclusively reveal actress Lena Dunham is so heartbroken over her breakup with Jack Antonoff that she still has the record producer on speed dial — even though Antonoff wants her to lose his number!

“She calls Jack at least five times a day, all in the name of ‘friendship,’ ” a pal told RadarOnline.com. “And she always talks to him right before she goes to bed. It’s so weird!”

After the two called it quits on their five-year romance in January, they vowed to stay friends. But now, our source claims Dunham “wants to get back to where they were.”

Over the past few months, the actress has been reminiscing about their relationship via social media. She even posted a “potential baby name list” she and Antonoff, 34, made together in 2015.

And while Dunham claims it’s perfectly normal to keep uncomfortably close to her ex, there’s one person who’s not so pleased: Antonoff’s new galpal, model Carlotta Kohl, who refuses to get serious with him until he kicks his ex to the curb.
