Actress Jennette McCurdy ended her brief romance with basketball star Andre Drummond due to a lack of chemistry.

The iCarly star, 21, struck up a flirty friendship with the Detroit Pistons player over Twitter.com last summer (13) after the sportsman made it known to fans that he had a big crush on her.

They went public with their fledgling relationship in September (13) when they were photographed leaving a Los Angeles restaurant together, hand-in-hand, but MCCurdy admits their romance fizzled out after a disappointing first kiss - and she ended up dumping the 20 year old days later over the phone.

Opening up to U.S. host Pete Holmes on his Nerdist.com podcast, she said, "It only lasted like a week, it was really short."

Asked about their initial smooch, she replied, "It just didn't go great... no sparks. The mouths... the shapes weren't right."
