"We kept walking and we got to the front of Federal Hill Park and he said, 'You know how I'm always fooling around with you, playing practical jokes on you?' Then he got down on one knee and he asked me. I just stared at him. And then I said, 'Of course!'" she says.

"And she went from angry to happy," he says, with a laugh.

"We didn't tell anyone until Christmas," she says. "So, I couldn't wear the ring around anyone. I would wear it to bed, and then have to take it off. Christmas Eve, we went tailgating at Ravens Stadium with my family and everyone. So, I wore gloves all day so I could wear it. [The next morning,] I had Josh come over to the house at 6 a.m. I have young siblings who would want to open presents early. So, we had to get in there to tell my parents before all the present-opening began. After we told them, my mom brought down a few extra presents that she said she had gotten 'just in case.' It was a picture frame with a big ring on it, and a bridal magazine. Then we went and told the rest of my family and Josh's family also."

The wedding: Planning the big day has definitely been a joint effort.

"We did everything together, and always went with our first choice," says Josh. "We just wanted to have fun and everything to be great,"

That began with the heads-up they gave their invitees.

"We had really fun save-the-dates. They were refrigerator magnets from magnetstreet.com," says Cortlyn.

The couple also ordered their invitations from magnetstreet.com.

"Josh did all of the invitations by himself," says Cortlyn. "He wrote all the addresses and sent them all out when I was at work one day."

On September 4, as some 100 guests arrive at the Gramercy Mansion, they'll be serenaded by singer/pianist Paul Lavin, who will then deejay at the reception. Cortlyn's uncle, James Kaiserski, will officiate at the ceremony, which will take place in the garden.

"He had [performed] a wedding for a friend in Massachusetts," says Cortlyn. "I wanted something personal. He became a minister online so he could do it."

Her maid-of-honor — 12-year-old sister, Gretchen — will wear an iris satin strapless knee length dress from David's Bridal and carry a purple, white and green bouquet.

A 9-year-old cousin, Adelaide Parrott, will be the flower girl, wearing a white floor-length dress with a little beading on it.

Cortlyn isn't revealing much about her gown, except to say it's "white, with a cathedral train."

Both she and Gretchen will wear dark purple pumps. Cortlyn's bouquet will be similar to Gretchen's.

"Mine will have more purple in it and hers will have more white, to balance it out," she says.

Williamson's Nursery is doing all the bouquets and arrangements.

Josh's best man (his 21-year-old brother Sean), head usher (Cortlyn's 10-year-old brother Dexter) and ring bearer (Cortlyn's 8-year-old brother Vincent) - will wear gray tuxedos with iris vests and ties. Josh will wear a gray tux with white vest and tie. All the tuxes are being rented from Cy's Swimwear and Tuxedos.

"I'm wearing dress shoes for the ceremony," says Josh. "But, then I'm switching for the reception to purple Nike shoes because the dress color is purple. They have "I do" on one side and the wedding date on the other." He ordered them from http://www.nike.com.

Cortlyn and Josh said the mansion itself has so much decor, they didn't need to add much for their reception.
