Kim Kardashian's brother Rob,allegedly has gained nearly 46kgs in the past year.
It is believed Rob Kardashian's struggles started after his split with singer Rita Ora, whom he accused of cheating on him.
But it seems Rob Kardashian is committed to shedding the extra weight.
The 27-year-old is flying out personal trainer Gunnar Peterson to Paris, France this coming weekend to keep him fit during sister Kim's wedding festivities.
The celebrity trainer told the website he is flying to the French capital to train Rob and his sister Khloe on Friday, Saturday, Sunday and Monday.
Gunnar said Rob was training five days a week, but scaled back to twice a week a fortnight ago because of his busy schedule.
Rob took a step back from public life last year amid reports he had sought professional help for emotional issues and weight struggles.
While the sock designer looked sullen as they arrived at the airport in Los Angeles, California, he obviously was not going to let anything stand in the way of him flying to France for Kim and Kanye West's May 24 nuptials.
