After a fairy tale wedding, newlyweds Charlie Sheen and Brooke Mueller are on their honeymoon and already talking about starting a family, or, as Mueller put it, "the next step".

Although the new couple denied the recent reports saying they are already expecting, Sheen underlined the fact that they are not expecting “as we speak," but that doesn’t mean it’s not in the cards.

When asked by Extra about “the plan” and how “extensive” it is, Mueller said:

"Hopefully triplets!"

"Could you imagine if I really had triplets? He'd be like, 'Whoa!'"

Sheen is already father to three daughters: Sam, 4, and Lola, 2, with ex-wife Denise Richards, and Cassandra, 23, with ex-girlfriend Paula Profitt.

Sheen, 42, and Mueller, 30, wed last Friday in front of about 60 close friends and family. Grey's Anatomy star Eric Dane and actress Rebecca Gayheart, who introduced the newlyweds to each other also attended the ceremony.

After the wedding, the couple flew to Costa Rica Sunday morning on a private jet. The couple didn’t wander around the place. The two went back to the romantic spot where Sheen proposed last July.

"It had sentimental meaning to them," E! News reported citing a source close to the couple.

The newlyweds are chilling at a private villa in the Four Season Papagayo resort, E! News reported. The villa features vaulted ceilings, marble bathrooms and even comes with its own butler.
