Faye and Aaron have been flirting in the house for a number of days, but the duo appeared to move apart after Aaron shared a kiss with Maisy James.
Aaron even threatened to walk out of the house earlier this week after he upset Faye and Tom O'Connell by kissing Maisy.
However, after an evening of teasing from their housemates about their affections, the two shared an intimate clench under the duvet.
Speaking to Faye and Aaron in the evening, Jay McKray said: "You proper fancy each other, just tell the truth!"
Chatting up Faye in bed before the kiss, Aaron said: "You know when you were washing in the garden and dancing, you looked proper sexy when you were doing that."
Aaron faces eviction on Friday against Aden Theobald and Heaven Africa.
