Kris Jenner has broken her silence on Caitlyn Jenner.

The Kardashian matriarch was one of the few members of the family who had not given a reaction to Caitlyn's debut on the June cover of Vanity Fair.

Attending MailOnline's Seriously Popular party on Wednesday (24 June) at the Cannes Lions Festival she opened up for the first time, describing Caitlyn as "beautiful."

The 59-year-old told Extra that Caitlyn's magazine's cover was "truly inspirational."

"I think it's amazing. I think that someone following their dream is truly inspirational to a lot of people.... you have to do what makes you happy," she said.

Kris was interviewed for the Vanity Fair feature in which she talked candidly about her ex-husband's struggle to transition in the glare of the media.

She told the magazine: "He was married to me and he wasn't who he wanted to be so he was miserable."

The momager revealed that she knew nothing of Bruce's desire to live as a woman until they got divorced in 2014.

"Why would you want to be married and have kids if this is what you wanted since you were a little boy? Why would you not explain this all to me?" she commented.

Caitlyn, 65, claims Kris always knew Bruce dressed in women's clothing and had been using hormones for several years.

It seems now, however, it's all water under the bridge for the former couple who share today a mutual respect for one another. Caitlyn tweeted: "Reading the VF article reminded me of the love & good times Kris & I shared for so many years."

Kris attended the lavish event with boyfriend Corey Gamble, and her daughters Kim, 34, and Kylie, 17.

Revealing how the family celebrated Father's Day, Kim said: "We just hung out and had dinner and it was a great experience. It was normal. It was like nothing was really different. I think everyone is adjusting really, really well and that's amazing and we're all so supportive. Everyone has their own journey with it, and we all respect each other's opinions and feelings."

Asked whether her relationship with her father had changed, Kim revealed: "It's a different one. We're definitely closer and I understand her a bit better, and her struggle. I respect all of her decisions, and I think it's great that she can be so honest and brave and be who she wants to be."

Looking elegant in a cream shirt dress and wedge heels Caitlyn shared a picture of the happy family gathering at her Malibu home on Twitter along with a message of gratitude.

'Great day yesterday for Father's Day,' she wrote. 'We had so much fun off-roading. So much love and support! Love my family!'

The portrait included Burt Jenner and his girlfriend Valerie, Brandon and Leah, Kim, Kanye West and North, as well as Kendall and Khloe.

Caitlyn's children Brody, Cassandra, Kylie and stepchildren Kourtney and Rob Kardashian weren't in the picture.

Kendall and Kylie Jenner paid their own heart-warming tributes to Caitlyn Jenner on Father's Day.

All of Jenner's children are expected to accompany her to the ESPY Awards on 15 June when she will make her red carpet debut.

The reality TV star will be honoured with the Arthur Ashe Courage Award at the event – an accolade presented to those whose contributions transcend sport. Past recipients of the award include one of the first openly gay NFL players Michael Sam, boxing great Muhammad Ali, and politician and philanthropist, Nelson Mandela.
