According to sources, the couple have been living apart for several months now and the break up was due to infidelity.
Insiders say that Toyin found out by looking at Niyi's phone, that's when she found out he had been in hotel rooms with different girls.
Adeniyi was said to have cheated a lot of times and she saw the evidence on his phone.
The couple are said to have moved on, they are no longer living in their apartment in Lekki.
Only close friends were aware of the breakup and it's alleged that a reconciliation might not be possible because of the ease with which both walked out and have indicated that they do not wish to be together.
One source said, "when there is no respect in a marriage, when couples talk to each other without respect and words are no longer relied upon and love has left behind a sour taste, then its time to check why you married in the first place."
In February 2013, Toyin and Adeniyi had a low key traditional wedding in Ibadan and on July 8, 2013, they sealed the deal at the Ikoyi registry, they had no child together.
The Yoruba actress, whose marriage to the younger Adeniji, was her second attempt at marriage says people should walk in her shoes before judging.
