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

1. The on-air prank call that left Jackie O fuming.

Talk about kicking someone while they’re down.

Football star-turned-media presenter Beau Ryan pulled a savage prank on fellow KIIS FM host Jackie ‘O’ Henderson yesterday, just days after she announced the breakdown of her 18-year marriage.

In a recorded phone call aired on The Kyle and Jackie O Show, Ryan duped the 43-year-old into thinking he was taking an anchor gig at rival station Triple M.

“I went and met the team… Anyway, I pretty much agreed to fill in for Matty Johns starting next year,” he said.

After a hellish week, the news tipped Jackie O over the edge.

“What the f***?” she yelled. “What do you mean? You want to do that? You just said to me the other week you didn’t want to work anywhere else.”

Ryan told the mother of one that he’d signed a five-year contract and would be raking in $1 million a year.

When a clearly furious Jackie O asked why he’d made the move, he went harder: “It just feels their talent on air is a bit younger than you guys,” he said. “It just feels a bit more me. You guys are a bit older and that.”

Mate. No.

“Ah, OK, thanks for the f**king old joke again,” she seethed, before the call ended.

When playing the clip on Friday, Ryan conceded his timing might have been a little off: “You were in the foetal position. I probably shouldn’t have done it yesterday. I probably should have waited a couple more weeks.”

2. The Kardashians have released some pretty dramatic footage of the moment they found out about Tristan Thompson’s cheating.

The Kardashian-Jenners aren’t immune to a scandal – there was Kylie’s wheelchair photoshoot, Kim’s weightloss lollipops, Rob’s revenge porn. But this one was different. Because for one, it wasn’t self-inflicted.

It was April 10. Khloe Kardashian was days from giving birth when footage emerged online showing her basketball star partner, Tristan Thompson, publicly exchanging saliva with a woman. A woman who definitely wasn’t her.

The reports left fans reeling. As for the family’s inner circle, well, courtesy of a snippet from an upcoming episode of Keeeping Up With The Kardashians, we now know what happened the precise moment the tabloid bomb dropped.

Here’s how each of them reacted…

Kim: “Khloe’s going to die.” [texts everyone] “She’s literally going to go into labour over this.”

Kendall: “I’m, like, in shock right now. I don’t even know what to say. What an idiot.”

Kylie: “I’m the one that told Khloe. I didn’t want to hurt her feelings, but I felt like she should hear from one of us, versus on the internet.”

Kourtney: “I mean, I can’t even imagine being in Khloe’s shoes. Just, like, how reckless it all seems. This is really shocking and obviously heartbreaking. The whole thing makes me disgusted.”

And then…Scott Disick: “Bro. That’s pretty serious, isn’t it?”

3. It looks like that Spice Girls reunion tour is actually going ahead after all.

I'll tell you what I want, what I really really want... what people all over the world have been waiting for for YEARS. A. Spice. Girls. Reunion.

And, I never thought I'd say this, but...the dream is imminent.

Rumours have been growing for the past year now that there's been some reunion talk brewing for a while, and the Spice Girls are apparently planning to announce via a video recording a 'huge UK stadium tour' on Monday.

EEK.

There's just one catch.

Victoria Beckham, AKA Posh Spice, will NOT, I repeat, NOT be reuniting with Geri Horner, Melanie Chisholm, Melanie Brown and Emma Bunton on November 11 on the Jonathon Ross show.

Yep.

Despite not jumping on the reunion bandwagon, 44-year-old Beckham continues to say that there is no bad blood between her and any other band members.

The last time the Spice Girls performed together was at the 2012 Olympics, and can I just say one thing? IT WAS EVERYTHING.

4. Alec Baldwin has been arrested after allegedly punching a man in the face over a parking spot.

60-year-old actor Alec Baldwin was arrested on Friday after he allegedly punched a fellow New York resident who stole his parking spot.

The outburst occurred on E. 10th Street, only a block away from Fifth avenue in the middle of the afternoon.

According to Page Six. a Baldwin relative was minding the spot just as 49-year-old Wojciech Cieszkowski, driving a black Saab station wagon drove into the spot.

Witnesses said that Baldwin was yelling expletives, including 'F*** off' during the ordeal.

It was when Cieszkowski walked to the meter to pay for the spot that Baldwin supposedly ran up to him and punched him.

30 Rock actor Baldwin was since arrested and charged with assault in the third degree. As he was leaving the precinct after the arrest, Baldwin's face was blank as he was hassled by reporters.

And, as all celebrities and now presidents do, he wrote a series of tweets on twitter in order to clear his name.

"Normally, I would not comment on something as egregiously misstated as today’s story. However, the assertion that I punched anyone over a parking spot is false. I wanted to go on the record stating as much," he wrote Friday evening.

"I realise that it has become a sport to tag people w as many negative charges and defaming allegations as possible for the purposes of click bait entertainment. Fortunately, no matter how reverberating the echoes, it doesn’t make the statements true," he added.

5. Literally all the best celebrity looks from Derby Day 2018.
