Meanwhile things got a little explicit on a boat ride between Lottie and Alex on Friday.
Setting sail on an ironically-named Bottom Party Boat, Lottie couldn't help but pull down her beau's swimming shorts as he stood over her at the back of the boat.
In turn, she revealed the Made In Chelsea hunk's toned posterior for all to see, as he grabbed hold of his lilac shorts and tried to keep his modesty covered up.

But Lottie was determined to get them off, as she was seen yanking at the shorts, capturing the attention of their boating companion Jess Woodley, who co-stars on Made In Chelsea with Alex.
Alex, 25, even had to steady himself by grabbing onto the boat rails as Lottie clawed at the shorts, trying desperately to unclothe her boyfriend in front of Jess, 20.
Their flirtatious shenanigans didn't stop there.

At one point, Alex and Jess were both seen on their backs, at the stern of the boat, legs in the air, while Lottie clutched onto them howling with laughter.
Later, she stood behind Alex as he sat down and climbed onto his shoulders, straddling his neck.
Jess looked on and appeared to dance for the duo, her arms outstretched, drink in hand.
At one point, the presumed captain of the ship - a gentleman in a red T-shirt - was seen approaching the threesome, potentially telling them to be careful as they larked around at the back of the boat.

The trio were joined by others on the boat, including a woman in a black swimsuit who's attention was peaked as Lottie tried to take off Alex's shorts.
In a quieter moment, Lottie was seen teetering on the edge of the vessel, looking down at the clear waters, perhaps contemplating whether or not she'd like to take a quick dip.
Earlier on, the three celebs were seen in the sea, with Jess joining the lovebirds in the water for a cuddle, wrapping her arms around both of them in a bizarre embrace.
Determined not to be left out, the flirty blonde nuzzled up to Lottie and MIC Lothario Alex.

Clad in a mismatched bikini comprising a navy top and yellow, frill embellished briefs, she wrapped her legs around gal pal Lottie and threw her arms around Alex's neck.
Lottie didn't seem to mind, and there certainly appeared to be no rivalry between the girls.
Kate Moss' half-sister also rocked a mismatched bikini - seemingly borrowing her briefs from Jess.
She teamed the itsy bitsy grey garment with a beige top in the same sporty style.

Hiding behind a pair of white rimmed, cat eye shades, the blonde bore a striking resemblance to Jess.
Alex certainly appeared to be enjoying himself as he relaxed on his exotic break, splashing around in the sea with the girls.
Alex and Jess formerly dated before he shared a highly-publicised relationship with co-star Binky Felstead.
When Jess joined the Made In Chelsea cast in 2015, it was revealed that Alex had been texting her behind then-girlfriend Nicola Hughes' back.

In the end, in order to appease Nicola, Alex told Jess on camera: 'We can’t really talk anymore' and seemingly ended their friendship.
However, since ending his relationship with Irish beauty Nicola, Alex has been spending a lot more time with Jess.
Lottie and Alex have been linked since early October when it was falsely believed that she had rekindled the flame with ex-boyfriend Sam Prince.

The unlikely pair enjoyed a string of dates together and have fast become inseparable.
Lottie has been mingling in the same social circles as the MIC crowd, partying with the likes of Topshop heiress Chloe Green, who previously appeared on the show.
The blonde beauty has been linked to several suitors in the past - having enjoyed lunch in June with pop star Conor Maynard, and flirted with Geordie Shore star Ricci Guarnaccio on Twitter.
