LOVE ISLAND ALL STARS TONIGHT: TUESDAY 21 JANUARY, FULL EPISODE RUNDOWN

Here's a rundown of what happens on tonight's episode of Love Island All Stars, which continues on ITV2 and ITVX.

GRACE AND NAS ARE FELINE THE SPARK AS CATHERINE GETS EMOTIONAL 

Interested in talking to Nas again, Grace pulls him to the bean bags for a chat telling him: “I’ve got to put in a bit of work don’t I, I’m a bombshell, got to live up to my name!”

Nas tells Grace he’s got cats and Grace says: “I’m a cat person and I say that quietly because a lot of people think it's a red flag… I think in my past life I was a cat… I'm being dead serious!”

Nas finds this hilarious, Grace adds: “I’ve got the traits… you don’t really know what they’re thinking and if they don’t want to be around you they wont…”

Nas adds: “Yeah and they gravitate towards people that feed them… I’ll just know to feed you to keep you around!” 

They share a laugh together and things seem to be going well for the pair but Catherine isn’t feeling she’s getting enough from Nas.

Talking to Elma separately Catherine says: “It’s nice to feel wanted and I just don’t, I know Nas is a slow burner… it's just starting to get to me.” 

As Catherine gets emotional, Elma reminds her: “What would you say to me? You're a boss ass b***h, 20 out of 10… if Nas isn’t giving you what you want someone else will!”

Catherine admits: “I want him to… I don't want it to be a thing, when it’s time I will say something if I need to.” 

RONNIE PULLS RON UP ON HIS COMMENTS TO ELMA

Elma tells Ronnie about her chat with Ron yesterday explaining: “He basically said to me that I exaggerated over the way I reacted about everything”. 

Ronnie later heads to the terrace. He interrupts Ron chatting to Kaz to discuss the conversation. Ronnie tells him: “I feel like you’ve come in as a bombshell, there’s a few things with Elma… it's like you have thrown me under the bus.” 

He adds: “I’ve got the hump tonight, I’m telling you it’s p***ed me off.”

It’s Ronnie vs Ron - will the boys move past things? And how will Elma react to their chat? 

AL-PACK-A YOUR BAGS - CURTIS AND EKIN-SU HEAD FOR THEIR FIRST DATE WITH SOME FURRY FRIENDS 

Curtis and Ekin-Su have been going from strength to strength and when Ekin-Su gets a text, things get even better.

She reads: “Ekin-Su, it’s time for you and Curtis to head out for your first date. Please get ready to leave the Villa. #FirstDateFeels #Al-Pak-A-YourAGame” 

Curtis says: “I’ve been wanting to go on a date, a different vibe just us two on our own.” 

They arrive at the Alpaca barn and Ekin-Su immediately points to two of the animals whose fleeces match their outfits, saying: “It’s me and you!”

After spending some time with the alpacas the pair enjoy a quiet drink, and talk turns to the outside world.

Ekin-Su asks: “Do you think your friends would approve of someone like me?”

Curtis replies: “Of course they would approve of you, you're bloody awesome!”

As the date draws to a close, will it be sealed with a kiss?

SCOTT AND TINA TAKE THINGS UP A NOTCH AND HE GETS A TEXT

During the day. Scott tells Tina by the pool: “I feel relaxed, I feel chilled, a completely different experience with you and I like your vibe a lot.”

Tina adds: “I’m a happy person but I think you're making me happier… I'm enjoying getting to know you every day.” 

The pair enjoy their first cuddle on the lounger. Then, later that evening, Scott and Tina share their first kiss.

Scott gushes: “That was worth the 9 year wait!”

Tina says: “I just got giddy!” 

But their first kiss bubble is burst when afterwards, Scott gets a text. 

He reads: “Can all Islanders gather round the firepit immediately.” 

Plus - at the end of tonight’s episode viewers will find out that it’s the first public vote of the series. Viewers will be given the chance to vote for who they think is the most compatible couple, with the results leaving one couple vulnerable…    

Love Island All Stars airs Sun-Fri at 9pm on ITV2 and ITVX.
