A source at London celeb hangout Chiltern Firehouse said: “Leo and Lottie were having a great time and seemed really close.”
Leo was spotted with Lottie at a glitzy celebrity hangout before they apparently left together.
The pair arrived within minutes of each other at hotel and restaurant Chiltern Firehouse in central London on Tuesday evening and partied into the early hours of yesterday.
Leo and Kate Moss were both 19 when snapped together in 1993 — sparking rumours they were an item.
Lottie was born in January 1998 and shares the same travel agent dad Peter as her half-sister.
A source said of her secret date: “Leo and Lottie were together most of the night and seemed really close.
“They arrived separately, but within only a few minutes of each other, and were on a table with other friends.
“But although there was a big group of them they only seemed to have eyes for each other.
“He is known for his fondness for younger women, particularly those under 26.
“One clubber even looked up Lottie’s birthday and worked out that she turns 26 in January.
“So there were a few jokes about how she had apparently hooked up with Leo just in time.
“Lottie looked gorgeous in a leather outfit and fake fur jacket so it was not hard to see the attraction for Leo. A lot of people were talking about how stunning she looked.”
