Nicole knew Lewis had no plans to marry her, she's completely gutted and feels lost about her future."WORK COMMITMENTSThe paper went on to say that both partners had denied any split. Friends say they have not been seen together for a few weeks and Lewis' last Instagram post of them both was a month ago with Nicole's just a few days before.
