Shanann Watts was planning the perfect gender reveal party in the weeks leading up to her brutal murder at the hands of her husband Chris Watts, financial records uncovered by the Daily Mail reveal.

The mom of two splashed out hundreds of dollars for a cake, cookie arrangements, party supplies and flowers.

But she pulled the plug on her plans just 11 days out from the celebration after Watts admitted he did not want a third child, according a series of heartbreaking texts.

Shanann, 34, had arranged for a party for around 50 people to be held at the family’s home in Frederick, Colorado, on August 19, 2018.

Credit card records show that she purchased a cake and other party food from Costco for $482.94, an cookie arrangement for $124.37, plus $89 worth of flowers and $168.40 worth of party supplies.

But the event was canceled on August 8 and instead of celebrating their impending arrival, Shanann asked her husband for a divorce.

Five days later and at 15 weeks pregnant, she was dead. Watts strangled her before fatally suffocating their two daughters Bella, four and Celeste, three.

The Daily Mail has obtained tragic texts Shanann sent to a friend revealing her anguish over her marriage in the run up to her murder.

‘Chris told me last night he’s scared to death about this third baby and he’s happy with just Bella and Celeste and doesn’t want another baby,’ she texted one close friend just hours after she had gone shopping for the party on August 7.

‘He said we’re not compatible anymore. He refused to hug me after he said he will try to “work it out.”‘

In another message on the same date, Shanann wrote: ‘I grabbed his hand during ultrasound and he didn’t grab back.’ 

A disappointed Shanann decided to call off her party and disinvited her guests – but did not get a refund for the hundreds of dollars she had spent.

She had entrusted her friend Nicki Atkinson as the only person who knew her baby’s gender.

Had the celebration gone ahead, Shanann would have learned she was carrying a boy by popping a balloon which Atkinson would have filled with blue confetti.

The couple had settled on the name Nico for their unborn child, which many have pointed out was eerily similar to the name of Watt’s mistress, Nichol Kessinger.

Shanann’s family said the name was actually a nod to her Italian heritage.

Shanann canceled the party and later on August 7 asked Watts for a divorce after voicing suspicions he was cheating to a friend.

‘I haven’t slept most of the week. My eyes burn from crying so much,’ she wrote in a text to a friend. ‘I canceled gender reveal. Nicki is going to tell me [the baby’s gender] today. I need happy news today.’

‘This baby in my belly deserves his full love either way,’ she added.

But she never got to welcome Nico into the world.

The next day, Shanann headed to Arizona on a business trip, texting friends that she would figure things out upon her return.

According to Watts’s confession, Shanann returned home from her trip early on the morning of August 13 and the two had sex just hours before he went on to murder her.

The couple began arguing about their relationship and Watts confessed that he was having an affair.

Angry and hurt, Shanann allegedly threatened to take her daughters with her when they split. Watts admitted that he then strangled her in the bedroom of their home.

He wrapped her lifeless body in a blanket and dragged her down the stairs of their upscale home in Frederick, Colorado. He loaded her into the back of his truck.

Watts then bundled up his little daughters and put them in the passenger side of the truck. He drove to a job site at Anadarko, the oil company where he worked. There, he buried his wife in a shallow grave near an oil tank.

Watts would later tell police that he then turned on his daughters, smothering Celeste while Bella begged him to stop. Then he smothered Bella and dumped their little bodies in separate oil tanks nearby.

The family’s upscale home in Frederick, Colorado was to be the site of a massive gender reveal party for the couple’s unborn baby boy, Nico

Watts then went on the local news after claiming that his family was missing and begged for their safe return.

But authorities weren’t buying it. They soon deduced that Watts was responsible for eradicating his entire family.

In a recorded confession, Watts gave an alleged motive: he had been carrying on an affair with a coworker Nichol Kessinger who thought he was separated. He later said that he killed his family because he wanted to be with his mistress.

After pleading guilty to the murders, Watts was sentenced to life in prison. He is being held in Wisconsin without the possibility of parole.

Last year the Daily Mail revealed the murderer’s prison letters in which he claims God has forgiven him for his sickening crimes.

‘I am a new man,’ he said in one letter viewed by the Daily Mail, whose recipient asked not to be identified. ‘I am not the person who committed those horrible acts.

‘I know that God does not see me as a sinner who killed his family; he sees me as His child.’

However, Watts is not an entirely changed man and has persisted with his womanizing ways, exchanging letters with around a dozen women on the outside according to his former cellmate.

The inmate described how the murderer would routinely become fixated on various women.

One admirer, who asked only to be identified as Deborah, told the Daily Mail Watts believes he has a divine purpose and likens himself to Jesus.
