It's official! Kylie Jenner throws her OWN baby shower a day after sister Kim Kardashian's party (Details, pics)

Kylie Jenner has thrown her own baby shower. The 20-year-old beauty was seen hosting her very own fete in her Hidden Hills, California mansion on Sunday as she was seen in silk pajamas in her backyard which was heavily decorated with pink flowers.

This comes one day after her sister Kim Kardashian threw her baby shower at her Bel-Air, California home that recently sold for nearly $18m. Kim, 37, is expecting her third child with husband Kanye West via surrogate in February.

Kylie had on a cream colored silk pajama set as did her mother Kris. Kim was also reportedly there. They were in Kylie's back yard making arrangements that included a bar and a big light pink tent.

Kylie has yet to admit she is expecting her first child with rapper Travis Scott, though she did seem to flash an engagement ring over the weekend.

There were several white tables and pink flowers. Her swimming pool was also filled with pink flowers. And the reality TV icon did not share her party on social media.

According to a People source, the theme of Kylie’s pink baby shower was 'pajama party,' similar to the one Kim threw in 2015.That was when she was expecting her son Saint. Kim already has daughter North, aged four.

A People source added that Kylie had been planning her shower 'for a while' and at the last minute Kim decided to throw her shower the day before, which seems like odd timing.

It is not known if TV cameras for KUWTK were at Kylie's fete.

Kim 'decided early last week to throw her own shower on the same weekend as her sister.'

Mindy Weiss was the party planner for Kim; it is not known who Kylie used. 'It was a last-minute baby shower. Guests received an invitation earlier this week. It was a low-key celebration with family and close friends,' it was added about Kim's event.

As far as Kim's party, it has been reported by People that her surrogate was not there.'

Kim was excited to celebrate. She can’t wait for her baby girl to arrive. They’re still deciding on a name — Kim asked guests to share their favorite names.'

Khloe is also reportedly pregnant with Tristan Thompson's baby, but has yet to confirm anything. There has been no sign of a baby shower for her yet.'

Even though this is a very exciting time for her, she wants to be more private for now and is doing her best to stay out of the public eye,' said the People source.

Meanwhile, Kylie has been trying hard to stay out of the public eye.

'She feels good, but her body is changing.
