Jonah Hill ‘so into’ ex-girlfriend

Jonah Hill and his former partner Jordan Klein were “passionately kissing” in public this week.

The 29-year-old This Is the End star called it quits with Jordan 18 months ago after spending three years together.

Apparently their romance has been reignited.

While ambling in the North Hollywood area of Los Angeles on Wednesday the pair’s affection for each other was palpable.

"They were walking toward Starbucks," an eyewitness told People magazine.

"Then the next thing we knew, he grabbed the back of her head and started passionately kissing her on the side of the street."

The couple were dressed casually when they entered the coffee retail chain.

While in the shop they are said to have ordered a latte, iced coffees and bagels with cream cheese.

The smitten pair were hungry for something other than caffeine and snacks however.

"As soon as they sat down they started kissing again," the source said.

"They were so into each other, it was like there was nobody else in the store, actually I think they forgot where they were, it went on for at least five minutes."

Jonah has known Jordan since they attended the same high school together in Santa Monica, California.

Their 2011 split reportedly came as a surprise to their friends and loved ones.

“They decided to break up, although everyone thought these two would be heading toward marriage,” an insider told Life & Style magazine at the time of their split.
