JLS fans may be upset that their idols split up today but do not worry, there is hope. Here are four bands who broke up but later reformed.
JLS star Marvin Humes has shared a photograph of his baby girl Alaia-Mai with his Twitter followers.
Marvin, whose wife Rochelle Humes from The Saturdays gave birth on Monday, wrote "Daddy's Girl" and posted a link to a picture of him beaming as he cradles his daughter:
Daddy's Girl...? http://t.co/oObf4IbAbv
Rochelle tweeted yesterday that Marvin is "a great daddy" who is "absolutely in love with his princess":
Marvin is a great daddy. Absolutely in love with his princess. Definitely a daddy's girl situation already started. So beautiful x
JLS are giving little away about life after the band splits, saying they're leaving their options open. Speaking to ITV's Daybreak, Aston Merrygold said he had heard rumours he may work together with singer Chris Brown.
But he added nothing had been decided. Aston said it was important to take time out after the band goes its separate ways.
There was devastating news for the fans of boyband JLS today after the group announced they are splitting up.
The X Factor 2008 runners-up will bow out with a farewell tour and a greatest hits album.
Sascha Williams reports:
Alexandra Burke, who beat JLS in the X Factor 2008 final, tweeted that she had "tears in my eyes" over the boyband's split.

A support group has been formed on Twitter to provide a forum for JLS fans to "unite and share their love" for the band.
One follower commented that they were "crushed" to hear about the band's decision to split, while another wrote "those boys have so much more to offer the music business".
He said it was "a good question" but he had not managed to ask the PM about his music views this morning.
