On Sunday’s episode of Keeping Up with the Kardashians, he lashed out at wife Kim‘s trainer for saying she “couldn’t imagine” seeing Kim at her goal weight of 120 lbs.. “She’s like, ‘There’s no way. I can’t even imagine you 15 lbs. lighter,’ ” Kim, 34, told sister Khloé Kardashian of her trip to the gym. “Kanye’s like, ‘Wait a minute. You are the trainer and you’re telling me you can’t imagine her 15 lbs. lighter? We need to get another trainer, then, because if I tell you she needs to lose weight in between her toe, you would have figured out a f—ing toe weight.” Kim has been open about her personal struggle to lose weight following the birth of baby North. She has said she gained 50 lbs. during the pregnancy and often posts “#TBT” photos on Instagram, wistfully recalling her “thinner” days. Keeping Up with the Kardashians airs Sundays (9 p.m. ET) on E!
