Ashton & Demi in June
The 'Two and a Half Men' star - whose marriage to Demi Moore has recently been rocked by infidelity claims - tweeted a link to a set of cufflinks engraved with the keyboard keys 'Ctrl' and 'Escape [Control and Escape] with the comment "If we are not looking for one we are looking for the other Ctrl Esc (sic)."

He also posted a drawing of a mouth with the caption "ahhhhhhhhhhh (sic)".

Ashton's cryptic twitter messages were posted after 22-year-old Sara Leal claimed today (12.10.11) that she had sex in a hot tub for "about two hours" with the actor on his wedding anniversary last month.

She told The Sun newspaper: "We had sex twice. Everything felt natural. We were having a good time. One thing led to another. He was good but it wasn't weird or perverted or creepy. I was attracted to him and he was attracted to me.
"He had great endurance. We were up for a while. It was about two hours."

Ashton and Demi are currently on a Kabbalah camping retreat and have not commented on the speculation about their marriage.
