kris jenner assumed Jay Z and Beyoncé Knowles skipped her daughter's wedding because they were working.

The 58-year-old reality TV star has hinted she was surprised that the duo opted to enjoy a quiet weekend in the Hamptons instead of travelling to Florence, Italy to watch their close friend Kanye West marry Kim Kardashian last month.

The 'Keeping Up with the Kardashians' star told Australian radio station KIIS 106.5 FM today (10.06.14): ''[I] just assumed they were working.''

The 'Holy Grail' hitmaker, 44, and the 'Pretty Hurts' singer were noticeably absent from Kim and Kanye's lavish nuptials, following rumours the groom had asked Jay to be his best man.

But Kris insisted that the high profile couple's decision not to attend didn't affect the celebrations.

She said: ''There was so much commotion and excitement, I never really gave that a second thought.''

She added: ''If you had been there, you would have thought that was the last thing on anyone's mind.''

Beyoncé, 32, posted a picture of Kim, 33, Kanye, 37, and their 11-month-old daughter North from their recent Vogue shoot on Instagram shortly after they exchanged vows, with the caption: ''Wishing you a lifetime of unconditional love. God bless your beautiful family.''

Insiders previously suggested that Jay Z and Beyoncé declined their invitation after her sister, Solange Knowles, attacked him in an elevator at a Met Ball after party in New York City on May 5 because he was allegedly flirting with Kim's close pal Rachel Roy, who was among the guests at the wedding.

A source said: ''Jay Z and Beyoncé were invited but didn't come, seemingly to avoid drama from Rachel Roy who was going. In the end, the wedding was full of love and super intimate.''

Kris is also friends with Beyoncé's mother, Tina Knowles, and attended her 60th birthday bash in New Orleans, Louisiana, in January.
