The former Hear'Say star was left devastated earlier this year when longterm partner Graham Quinn left her after six months of marriage. The pair kept the split quiet for months, but it finally emerged in June.
It was reported that pianist Myleene had pulled out of playing at JLS star Humes and The Saturdays singer's summer wedding, with sources claiming she couldn't face the ceremony.
However, the brunette beauty promised her pal that she would perform as planned, and Rochelle told Hello! magazine, "Myleene says she's still very much up for it, but we'll see how it goes. First and foremost she's our friend and I don't want to commit her to anything right now. Whatever she wants to do is fine with us."
But it has now emerged that Myleene won't be putting in an appearance at Saturday's nuptials at Blenheim Palace in Oxfordshire.
"Things are still raw between them and there's no way she'd want it to affect Marvin and Rochelle's big day.
"She's sent a gift and Rochelle knows she'd be there if things were different."
The wedding guest list reads like a Who's Who of pop - Olly Murs, Craig David, Pixie Lott and Alexandra Burke, as well as Rochelle's bandmates, are all set to attend.
