Kim Kardashian's ex-boyfriend has been begging her to get back with him.

Despite splitting from the 30-year-old socialite last year, NFL star REGGIE BUSH has reportedly been bombarding the brunette beauty - who is due to marry basketball ace Kris Humphries on August 20 - with "text messages and voicemails" attempting to persuade her he's "the one for her".

An insider said: "He's been sending text messages to Kim and leaving her voicemails, telling her she's making a mistake and that he's the one for her.

"In the past, Kim was friendly to Reggie, but now she's stopped responding."

Reggie is said to have been begging Kim to call off her impending nuptials, but the 'Keeping Up with the Kardashians' star is "burned" by the way their romance ended.

The source added to Life & Style magazine: "He was begging her to call off the wedding and give him another chance. She was burned by the end of their relationship, and she's truly moved on."

Kim made sure to tell Reggie about her whirlwind engagement before it hit headlines.

A friend said at the time: "Reggie was told about Kris and Kim's engagement this past weekend because Kim knew everyone would be contacting him for reaction.

"During their last break-up, Reggie told me Kim may have been the one who got away. He loved her to death."
