Myleene Klass and husband will both attend Rochelle and Marvin's wedding

This could be awkward for Myleene Klass and estranged husband Graham Quinn

Myleene Klass and her estranged husband will come face-to-face for the first time at the wedding of Rochelle Wiseman and Marvin Humes.

The Saturdays singer and Marvin from JLS are due to tie the knot at Blenheim Palace in Oxfordshire next month and both Myleene and Graham Quinn are expected to attend.

It emerged just last week that Quinn had walked out on Klass and their two children, Ava, four, and 14-month-old Hero, in April after six months of marriage, although the couple had been together for 11 years.

Myleene's 38-year-old ex is set to be an usher at the nuptials having been the tour manager for JLS for the last four years and Klass is good friends with Rochelle.

A source told The Sun: 'They’ve both got reason to be there. Graham is an usher, but then Myleene has grown close to Rochelle over the years.

'The feeling is why should she give up her invite when she’s done nothing wrong? She doesn’t see why she should shy away from it.'

We have a feeling Myleene will be planning a killer wedding outfit as we speak!
