Sheryl Lee Ralph and Vincent Hughes are planning a "big party" to celebrate their 20th wedding anniversary.

Sheryl previously admitted that because of logistics regarding both of their careers they actually end up seeing each other just once a fortnight but insisted that because they have been together for so long now, the setup has "worked" for them despite causing controversy amongst fans.

She said: "Vincent and I have been married going on 19 years. We've been together 21 years. 'Abbott [Elementary]' is shot in Los Angeles. My husband, as a senator, is always in his Capitol, so I don't know what magic people think we're gonna do. We see each other on the average of every two weeks.
