Khloé Kardashian reportedly begged brother Rob Kardashian to attend Kim Kardashian and Kanye West's wedding in Florence, Italy on 24 May.

The 27-year-old reality star skipped sister's wedding after she reportedly commented about his weight gain.

According to Hollywood Life, the 29-year-old Keeping Up With the Kardashian's star "was in tears" when she found out that Rob was not staying for the wedding.

"Khloe's hurt the most because she wanted her brother to be there, enjoying this special moment with Kim and Kanye and with the entire family," a source said. "[She] was crying herself — trying to convince Rob to stay."

"She even told him 'don't trip on what she's saying. She's getting married and is all nervous and freaking out,'" the insider explained.

Though Khloe told Rob to "forget about it," Rob did not listen to her request.

"In the end that wasn't enough to convince Rob to stay so he bailed," the source said.

The family was supposed to wear Valentino as they left France for Italy, but Rob didn't fit into that plan. He became upset and reportedly had a huge fight with Kim.

"Kim was bashing Rob about his weight and how he would ruin the pictures that would be taken with the family," another source told the publication. "It got back to Rob and he called her out."

"It got heated, and everyone decided to take Kim's side – Rob was devastated and left," the insider added.
