2008
During a year-long hiatus from Westlife in 2008, Egan launched a new venture with Louis Walsh to put together and co-manage girlband, Wonderland, which included Jodi Albert, who later became Egan's wife.

Westlife split up in 2012 after a Greatest Hits Tour.
In June 2012, Egan announced in an interview with the Sunday Life that he was "looking at doing a TV show with Sky on surfing".
Later reports suggested that the show would be eight episodes long and would broadcast on Sky1 later in the year.
In July 2012, Egan presented the British program This Morning's Hub regularly, standing in for the regular hosts.
Later that year, every Friday morning in October, he began giving reports on another British programme This Morning about the remaining contestants in the ninth series of The X Factor, before the competition's live shows that weekend.
On 21 October 2012, Egan co-presented the revamped version of Surprise Surprise, but did not return the following year.
2013
Egan was a judge and coach on The Voice of Ireland and won the thirteenth series of I'm a Celebrity...Get Me Out of Here! in 2013.
In his early musical years, Egan was part of a rock band named Skrod.
He can play at least five musical instruments, including guitar, piano, and drums.
He is a grade 8 pianist and was taught piano by his brother Gavin Egan, a university music graduate and full-time teacher of music in the UK.
Before he was in Westlife, Egan was part of a pop group called Six as One, which later changed its name to IOYOU, with fellow Westlife members Mark Feehily and Shane Filan, alongside Graham Keighron, Michael "Miggles" Garrett and Derrick Lacey.
After IOUYOU was signed by Louis Walsh, its lineup changed to include Egan, Mark Feehily, Shane Filan and two new members - Nicky Byrne and Brian McFadden.
The band's name changed to Westside and later to Westlife.
In 2013, Egan appeared on the thirteenth series of I'm A Celebrity...Get Me Out Of Here!.
He was ultimately crowned King Of The Jungle, which contributed to an invitation to being signed by Rhino Records to create his Home album.
2014
In January 2014, Egan signed with Rhino Records of Warner Music Group, and his debut album Home was released on 14 March that year in Ireland, and on 17 March in the UK.
His debut single "Home", a cover of a song by the band Daughtry, had its first exclusive play on BBC Radio 2 at lunchtime with Terry Wogan's show.
The album has peaked at number 2 on the Irish Singles Chart and number 9 on the UK Albums Chart.
In May 2014, Egan released the second single from the album, "I'll Be", a cover of the track by Edwin McCain.

From 5 to 9 January 2015, Egan and Angela Griffin co-hosted Fat Pets: Slimmer of the Year on ITV.
2018
In October 2018, Westlife announced the group's reunion as a four-piece.
2019
In 2019, the group headlined "The 20 Tour", named in honor of Westlife's 20th anniversary since its formation and the release of its first single, "Swear It Again", in 1999.
In addition to touring, Westlife also released new music.
"Hello My Love", the first single from the group's upcoming album, debuted on The Graham Norton Show in January 2019.
Egan was one of four coaches on The Voice of Ireland.
However, his dreams of winning the show went to tatters as he threw his lot in with Jim Devine, from Northern Ireland.
This immediately put him at a disadvantage to the other contestants as, ahead of the final, viewers in Northern Ireland could not download his single, the tally of which contributed to his vote.
Egan was left fuming and in need of support from Sharon Corr as he expressed his opinion on the unfairness of it all and had "huge rows" about it but to no avail.
