[1] Sinitta's mother is Miquel Brown, who was a popular Canadian disco-soul singer in the 1970s and 1980s and a member of the cast of Hair.

In 1987, Sinitta released the lead single from her upcoming debut album, after seeking the help of producers Stock Aitken Waterman (SAW).

[14] The product of that collaboration, "Toy Boy", was based on a tabloid headline about Sinitta's love life, and featured a rap written by the singer.

The success of the track came despite the singer initially expressing her dissatisfaction with the subject matter of the song when first presented with the idea by record label boss, Simon Cowell.

[citation needed] She appeared on the cast recording album for What a Feeling, a live recording taken from the Apollo Playhouse Theatre, Edinburgh, in May 1997, and replaced Irene Cara to tour with Sonia (a fellow former SAW artist) and Luke Goss (formerly of Bros) in the rock and pop musicals concert, What a Feeling[35] the same year.

In 1997, Sinitta recorded vocals for a cover of the Limmie & Family Cookin' hit "You Can Do Magic" with Mike Stock and Matt Aitken, believing it to be her comeback single.

[21] In 2004, Sinitta made her premiere appearance on The X Factor in the first series, when she assisted Simon Cowell at the Judges' Houses stage, helping to select his final three acts for the live show, choosing Verity Keays, Rowetta Satchell and the eventual series winner Steve Brookstein.

[37][38] In 2005, Sinitta helped Cowell once more during the second series, this time choosing the final four groups Addictiv Ladies, 4Tune, The Conway Sisters and Journey South.

[39][40][41] In 2009, Sinitta returned to the show again during the sixth series for the Judges' Houses stage, and then helped Cowell select Jamie Archer, Danyl Johnson and Olly Murs.

[47][48][49][50] In 2011, however, Sinitta assisted Louis Walsh for the first time, rather than Cowell, when she returned in series 8, selecting Jonjo Kerr, Sami Brookes, Johnny Robinson and Kitty Brucknell.

[51][52] In 2013, Sinitta helped Walsh on series 10 of The X Factor to select Sam Callahan, Luke Friend and Nicholas McDonald, who eventually finished second.

[54][55] The following year, Sinitta was announced as joining the cast of the first series of the Channel 4 reality TV show The Jump.

[57][58][59][60] Sinitta returned to her music career in 2014, with her comeback single being a cover of her mother Miquel Brown's song "So Many Men, So Little Time".

[62][63][64] Sinitta returned to The X Factor on series 11 to assist Simon Cowell again that year, when she helped to choose Jay James, second place finalist Fleur East and eventual winner Ben Haenow.

[69][70] Sinitta appeared in the hit reality TV show Ant & Dec's Saturday Night Takeaway as a recurring character in 2016.

[71][72] Alongside this, Sinitta became a series regular on the chat show Up Late with Rylan,[73][74] and also made appearances on Celebrity Masterchef as a contestant, although she was eliminated in Week 1.

[76] Sinitta took part in the 11th series of Celebs Go Dating but opted to leave the show in episode 14 after failing to find love.
