Kendall and Kylie Jenner are wedding belles at brother's Hawaii ceremony..

Kendall and Kylie Jenner proved to be quite the wedding belles at their half-brother's wedding in Hawaii yesterday. 

The teens acted as bridesmaids as Brandon Jenner's said 'I do' to Leah Felder, daughter of former Eagles guitarist Don Felder, in Kauai.

Kendall, 16, wore a flowing dress which exposed her back while Kylie, 14, was in a pale blue frock. Both had flowers in their hair.

Father of the groom Bruce watched on proudly while Brandon's famous stepmother Kris also attended, wearing a pink floral halterneck dress to the nuptials. 

Kim Kardashian and her sisters Khloé and Kourtney decided not to jet to Hawaii for the occasion, fuelling speculation that they 'snubbed' the big day.

Instead, the threesome were spotted going to lunch together in Sherman Oaks, California.

According to Radar Online, Kim, Khloé and Kourtney refused to go to the wedding, but a source dismissed this, telling them: 'There is no animosity, but the Kardashian girls just aren't super close to the Jenner boys.'

Kim kept her well wishes simple, by tweeting to her 14,822,171 followers: 'Congratulations to my step brother and his gorgeous new wife!'

Meanwhile, Khloé wrote on her blog: 'I just wanted to send a HUGE congratulations and so much love to my brother Brandon and his fiancé/soon-to-be wife Leah. Wishing you both all the happiness in the world!'

Kourtney added on her blog: 'I want to wish a huge congratulations to my step brother Brandon and his stunning fiance Leah who are marrying today. Sending my love to you both.'

Just married: The couple looked blissfully happy on their big day

However, the ladies clearly didn't care enough the big day to fly to Hawaii and watch Leah walk down the aisle.

But luckily, the rest of Brandon's family were there including his father Bruce Jenner, his wife Kris and their teenager daughters Kylie and Kendall.

The foursome were spotted swigging back POG juice - a tropical drink made from passionfruit, orange and guava fruits - as they arrived at their hotel in Kauai.

Brandon is one of Bruce's three sons from his second marriage to Linda Thompson, who was also in Hawaii.

Linda's ex-husband David Foster, the multimillionaire songwriter to whom she was married from 1991-2005, was also there.

Pretty in pink: Kris wore a floral dress for the occasion 

The former athlete was first married to Chrystie Crownover, with whom he had two children Burt and Cassandra.

His third son, Brody, was born in 1983 but less than ten years later Bruce wed Kris  - who already had four children with her former husband Robert Kardashian.

In 1995, Kris gave birth to hers and Bruce's first daughter Kendall, and two years later they welcomed Kylie into the world.
