Kim Zolciak flaunts tiny waist in $156 Alo Yoga outfit and reveals 'what Easter ... trends now

Kim Zolciak-Biermann gazed at her own reflection in - not one but - two mirror selfies she shared from her $880K five-bedroom Alpharetta, GA mansion on Easter Sunday.

The 45-year-old reality star - who boasts 6.3M social media followers - announced: 'Happy Easter, everybody!'

Kim (born Kimberleigh) had taken off her 'Easter clothes' and was wearing glasses as she flaunted her tiny waist in a white $58 Alo Yoga 'Alosoft Crop Finesse' top and the grey $98 Alo Yoga 'Chill Sweatpant.'

'Alo Yoga for the win!' Zolciak chirped of the possible paid partnership.

The Modere brand ambassador then aimed her cell phone camera at the Christmas decorations - or 'Christmas s***' as she put it - she had temporarily stashed in the corner of her bathroom.

Kim - who tousled her waist-length blonde hair extensions - is in the midst of a contentious divorce from her estranged second husband Kroy Biermann, and the couple have defaulted on their mortgage and owe money to the IRS, credit cards, and banks.

Financial woes didn't stop Zolciak from undergoing copious Botox injections at the Charette Cosmetics Medical Spa in Atlanta, GA on March 22 and a $125 VIP treatment at the Lavie Head Spa in Duluth, GA on March 12.

Rather than write a message about the Christian holiday herself, The Real Housewives of Atlanta guest star reposted Solomon Jordan's Notes app message about nine things Easter has taught him including: 'Forgive...even when it's hard.'

Meanwhile, Kim's daughter Ariana Lenee Biermann attended Easter Sunday services at contemporary Christian mega-church - The Free Chapel in Gainesville, GA - alongside her 'soulmate' Hudson McLeroy.

'Love loving Jesus w you!' the 22-year-old influencer gushed via Instastory. 'I love our church!'

Ariana Instastoried a video of 'our pastor' Jentezen Franklin playing saxophone during The Free Chapel's free original production - Easter: The Live Experience - which featured 'stunning visuals, live animals, and inspiring music.'

Zolciak welcomed Ariana during her 21-month marriage to ex-husband Daniel Toce, which ended in 2003.

The Florida-born socialite, Ariana, and her 27-year-old daughter Brielle Karenna Biermann (with ex-boyfriend John MacDougald) filmed a reality TV pilot in January, which is now being shopped around to networks like Bravo.
