This alleged couple couldn't keep its hands off each other while flying out to London

After their 'affair' became public last year, this couple has tried hard to maintain a low profile. We have now found out that the married actor and his non-industry ladylove took a secret trip to London to spend quality time with each other. Being far away from prying eyes, they couldn't contain their excitement and indulged in some serious intimacy throughout the duration of their journey.

A passenger, who was witness to the PDA, says, `The couple threw caution to wind and was seen passionately smooching each other. They even asked the cabin crew not to disturb them.`

The source adds that the couple's relationship did much damage to their respective marriages after which they tried to stay away from each other and reveals: `But they have been meeting off and on. They have had several clandestine getaways to foreign shores earlier too so that they can enjoy some privacy.`
