Celeb in 5: Sunday's best entertainment and gossip news.

1. Sia just shared the very, very graphic reason she was late for her concert.

Oh... this is brilliant.

Sia just shared with her fans the very ~ graphic ~ and slightly smelly reason why she was late for her concert.

The singer tweeted:

I may be five minutes late. We couldn't catch a plane due to weather, so drove thirteen hours then blew a tire which has given me crazy diarrhea. Bear with me guys. I love you.

Still on the road she gave her fans another lil' update"

Four minutes from venue. Fully dressed. Ready to go. Bear with me. Massive apologies.

Her fans, of course, bloody loved it.

“Omg it’s not called diarrhoea anymore but Siarrhea from now on," one tweeted back.

“Don’t worry Queen, we would wait the whole lifetime for you," added another.

Oh Sia, we've all been there. Right? RIGHT?

2. STOP EVERYTHING because it looks like Keira Maguire and Jarrod Woodgate are falling in love.

If this isn't a match made in reality TV heaven, we don't know what the hell is.

Apparently Jarrod Woodgate and his pot plant and Keira Maguire have gone on a date during the filming of Bachelor in Paradise - and sparks be flyin', people.

The pair appear to be sitting close together on a sun-lounger, and leaning in and chatting intensely with each other.

The couple-to-be (da da dum dum, da da dum dum) are currently filming the show in Fiji alongside other bachelor rejects past contestants including Leah Costa, Michael Turnbull and Megan Marx.

This is EVERYTHING we could have hoped for and more. Hurry up, 2018.

Excuse us, but in the era of extravagant children's birthday parties with think we just found the most lavish one.

On Saturday, Terry Biviano's four-year-old daughter Azura celebrated her birthday complete with a totally pink and white theme, matching family outfits and a giant unicorn for good measure. Oh, and perhaps a real life horse, too.

The party, which was held outside and in front of a lake, featured a long table set up with balloons on top and a specially styled centrepiece.

Azura wore a custom Victoria Novak unicorn crown which looked beautiful but perhaps as impractical as having a small golf club stuck on top of your head.

Posting on Instagram, the fashion designer wrote: "Happy Birthday to our beloved daughter Azura! Another year has passed & we are happy to see you grow even more beautiful & wiser each year. Our baby, our little girl, our sky blue tressure [sic], we adore you!!! No matter how old you are you will always be our baby girl! Our wish for you is to love life & never stop dreaming..."

But when your four-ear-old birthday parties are this good, why would she ever have to dream?

4. Elsa Pataky had a terrifying visitor in her home and it definitely wasn't Chris Hemsworth.

If Elsa Pataky wasn't totally acclimatised with Australia's wildlife, then perhaps this was the baptism she needed.

Taking to her Instagram story on Sunday morning, the actress posted a video of an unwelcome visitor at their Byron Bay abode.

A really freaking big snake.

"New guest in the house!" Elsa captioned video in an overly enthusiastic tone for someone who just spotted a lethal reptile just metres from her bed.

Here's hoping they all got out, you know, unscathed...

5. Welcome to the future: Meghan Markle’s exorbitantly-priced Strathberry tote sells out in minutes

How many people have nearly $900 to throw away on a handbag? Too many, it would seem.

When Meghan Markle made her very first official public appearance with fiance Harry, all eyes went from her coat to her dress to her - yes, you guessed - hand bag. And not of the Prince variety.

The bag, made by small Scottish label Strathberry, was in every photo of the former actress as she met with crowds in Nottingham on Friday.

“It’s just amazing for us, it really is the greatest,” a spokeswoman for the brand told the Telegraph.

“It was a fantastic surprise and we are really excited. We’re suddenly incredibly busy.

“The Strathberry midi tote tricolour is now sold out and will be restocking soon. People can sign up for notifications on our website.”
