An insider also said that they had a conversation with Kardashian not too long ago and he didn't seem to need professional help.

"He was in really good spirits, seemed very much himself. Said he'd been working out every day and was focused on getting back in shape."

Lately, Kardashian has made headlines after he opted out of joining his reality star family on a trip to Thailand. But he definitely let everyone know there were no hard feelings. When they returned back to Los Angeles he tweeted, "Mi Familia is home! Yeee!"

His older sister Khloe Kardashian replied to his tweet with a heart emoji.

Just days before that he shocked fans when he wrote, then deleted a cryptic tweet on March 31. "No one will ever understand how much it hurts."

Earlier this week, rumors swirled that Rob checked into the Dawn at The Meadows treatment center in Arizona to get help with his weight struggles and depression.

A source claimed, "Rob has checked into The Meadows for about a month for substance-abuse issues. He's been feeling stronger and more relaxed without the incessant berating from everyone."

They added that the goal was for him to change by the time Kim Kardashian marres Kanye West next month. They also claimed that he had an addiction to Sizzurp.
