Dylan McDermott and Maggie Q do not need to "stalk" each other anymore since they are now engaged to be married.

The "Stalker" co-stars have apparently put a ring on their relationship despite only dating for less than four months, Us Weekly has learned.

An insider claims that though McDermott and Maggie Q - born Margaret Denise Quigley - only began dating in October, the 53-year-old actor is so smitten by the 35-year-old actress that he popped the question just a few months ago.

The proposal reportedly took place while the lovely couple was enjoying their twosome vacation in Hawaii. A source revealed that although they are ready for marriage, they have not set a wedding date yet.

Back in October, rumors surfaced that McDermott and Q were already boyfriend-girlfriend after they were spotted spending a romantic night at Santa Barbara's Olio e Limone, Business Standard has learned.

The Hollywood celebs were noticeably flirting at each other that night and most of the time they exchanged kisses and smiles without minding the public.

"They were very flirty, smiling at each other, canoodling," an onlooker said at the time. "At one point she was feeding him at the table."

While this may be the first marriage for the "Insurgent" actress, this is not the first time the hunky actor is tying the knot. He was previously married to actress Shiva Rose, and their marriage even lasted for 14 years (they split in 2009).

McDermott is father to Rose's daughters: Colette, 18, and Charlotte, 9.

Both McDermott and Q are yet to confirm the engagement, but Perez Hilton reports that she already has the ring to prove it.

The notorious Hollywood gossip site even claims that back in October when McDermott proposed, he didn't seal it with a ring. The "Nikita" alum only received her new sparkler recently for some unknown reason.
