On Friday, she ended her 19-year marriage to former footballer Jamie Redknapp in a 25-second court hearing.
And Louise Redknapp showed the crowds at G-A-Y on New Year's Eve that she's now happily unattached, as she took to the stage to sing, dance and laugh her way into 2018.
The mother-of-two appeared not to have a care in the world as she put on an energetic performance before roaring with laughter as the clock struck midnight, bidding farewell to what has been a tricky year for the former Eternal star.

This comes after The Mirror reported that the 43-year-old was 'really excited to celebrate with pals out on the town – it’s the first time she’s ever done anything like this'.
Louise, 43, looked typically chic in an all-black ensemble consisting of a skirt and jacket suit, black tights and thigh-high leather boots.
Literally letting her hair down, the singer wore her chestnut locks loosely around her shoulders in light waves, and displayed a flawless complexion, showing off a healthy golden glow.
She added nude gloss to her lips and a smokey swish of shadowing to her eyes.

Louise's partying has come into question since news of a split surfaced as it was claimed in July that her friendship with party girl Daisy Lowe contributed to the split - as the 27-year-old helped the star 'rediscover her youth'.
Sources continued: 'She’s booked to perform some of her solo hits at GAY nightclub in London in front of friends. They plan to have a drink on the VIP gallery and enjoy the atmosphere and then hit up some other venues.
'She’s really going to let her hair down and celebrate the New Year truly meaning the start of a new chapter for her.'
Louise was seen living it up with pals on Thursday evening as she attended the wedding of Strictly Come Dancing's Artistic Director and Choreographer Jason Gilkison in Liverpool - just hours before the court hearing.
The end: She has just officially ended her 19 year marriage to Jamie Redknapp
News of her plans comes after it was claimed Louise reportedly filed for divorce from husband Jamie in March.
Insiders tell The Sun, she filed for divorce from the footballer nine months ago, just weeks after the end of the Strictly Come Dancing Tour. Her part on the show has been widely reported to have contributed to the split.
A source told the publication after the hearing: 'The marriage was over long before anyone previously believed.' Louise and Jamie were first hit with reports of marital woes in April, however insiders claim by this point she had already began legal proceedings.

MailOnline has contacted representatives for Jamie and Louise for comment.
The final dates on the tour were 11 and 12 February at London's The O2 Arena - just weeks before the alleged submission date in March.
Her participation in 2016's Strictly Come Dancing was widely regarded to have been a factor in the split, but it has been claimed that Jamie fully supported her decision to take part and encouraged her at each Saturday night show.
Jamie's unreasonable behaviour has been cited as the cause of the split, a reason he did not contest, however it has now been claimed the former footballer is unhappy with being solely blamed for their divorce, reports The Sun.
