An insider said: “Yeah, it was awkward and tense, but Kim couldn’t have been politer or nicer.

“You’d never think that anything like that had gone just the day before it – and when Kanye tried to bring it up with Kim, she told him it wasn’t appropriate to even discuss at Saint’s birthday party.

“She knows that the best way to shut Kanye down is to stay calm and not react.

“She smiled through the whole party like she wasn’t phased.”

Kanye, 45, is said to have spent “several hours” at Kim’s mansion to help Saint see in his seventh birthday.

Just days before the rapper claimed that he caught his ex-wife cheating on him with NBA star Chris Paul.

The Chicago native tweeted: “Let’s break one last window before we get outa here. I caught this guy with Kim. Good night.”

He included a photo of Phoenix Suns star Chris, 37, in the tweet.

Kanye did not provide any further details or context about the alleged cheating incident. There is no evidence to back up his wild claim.

That same day Kanye sparked outrage as he delivered a controversial interview on InfoWars with Alex Jones.

During the discussion, the Grammy winner appeared to continue his hateful anti-Semitic tirades toward the Jewish community, seemingly glorifying Hitler and the Nazi Party.

Last week Kim and Kanye finally reached a divorce settlement.

The former husband and wife reached an agreement on all matters, including child support, custody, and property division.

The Kardashians star and her fashion designer ex will share joint custody of their four children – North, Saint, Psalm, and Chicago and Kim will be paid $200,000 a month in child support.

Kim’s rep has been approached for comment.
