And according to reports there was another very special guest at the concert in the form of baby North West, who was hanging out backstage.

'Kim was very excited about being at the concert and supporting her man,' a source told In Touch. 'And Kanye thinks he did an amazing job at the concert in Oakland. The baby was great backstage and hung out with her mom.'
Both Kris and Kim were dressed similarly in black dresses, and Kris teamed hers with a pair of racy knee-high caged boots.
Meanwhile Ben was casually clad in a beanie hat, grey jumper and jeans.

Kris and her husband Bruce Jenner announced just two weeks ago that they had split after 22 years of marriage, revealing they had been separated for a year.
On Thursday she posted a photo on Instagram with her friend John and pointed out that Ben was also in her company with this caption: 'Fun night @johneddy83 here we go YEEZUS tour. #oaktown @benflajnik.'

A source close to the family tells MailOnline, 'They are not dating, they're just really good friends. They were with a big group of people.'

Big fan: It seems like winemaker Ben is particularly fond of Kanye's music and he was obviously having a great time

Plenty to celebrate: No doubt the group were toasting to Kim and Kanye's engagement which happened on Monday, as well as the success of his concert

But Kris has seen Ben privately at least twice before.
In September she visited him in Sonoma, California, where his family has a winery. The matriarch posted a photo on Instagram of the two sipping wine, alone with her friend Jonathan Cheban.
They were also reportedly hanging out together at Joe Francis' house in Mexico as well.
The reality star - who split from his Bachelor fiancee Courtney Robertson a year ago - told UsWeekly, 'I did Kris' talk show a few months back, brought my wines on the show. Of course I offered her a visit to the winery whenever she had a chance. That's how we met.'

He went on to say, 'Recently, she ended up contacting me about a month ago or so and asked me if they could film an episode of Keeping Up With The Kardashians at the winery. I of course obliged.
'I showed them around Sonoma. Who doesn't want to ride bikes and drink wine? That's where one of those photos were from.'
He said he was 'surprised' to learn Kris and Bruce split. 'I'm kind of caught in a crossfire,' he added to the publication.

He confessed that he's been dating a 'local' girl in North California who's in the wine business. 'She's super great and super smart. It's been a few months at this point.'
There have been no photos of Ben and his unnamed mystery woman to date.
One day we know Ben and Kris won't be together is Saturday. That's when Ben has an Evolve Winery event with Project Pink in Sonoma Valley and when Kris will be promoting Kardashian Khaos inside the Mirage in Las Vegas.
Unless they fly private jet, they won't be able to be in the same city at the same time.

A tabloid claimed earlier this month that Kris has a crush on Ben and was in 'full-on dating mode,' but she told TMZ 'there hasn't been a thought or a twinkle' about dating someone else. She claims she and Bruce have 'not discussed it.'
The Jenners have not made any steps toward divorce, but if they start dating again, 'they may have to reconsider their no-divorce situation,' according to US Weekly.
In addition to being in the company of Ben, Kris has also been seen out and about with Britney Spears' ex, former agent Jason Trawick.
