However the 32-year-old couldn't resist flashing her ample cleavage in the slinky scarlet dress, which featured long sleeves and a low-scooping neckline.

Nicki shared photos from her brother's nuptials on her Instagram page, and admitted she couldn't help shedding a few tears.

It might be the Anaconda hit-maker's turn down the aisle next, as earlier this year rumours that she is engaged to Meek Mill started swirling.

While she continues to sport a massive diamond sparkler on her wedding ring finger, Meek Mill denied that he had popped the question to Nicki in May.

Earlier this month, Nicki sparked pregnancy rumours when she referred to her other half as her 'baby father' during a performance, but sources told TMZ that she simply calls him that as a term of endearment.
