If you have a tween girl in the house, you're probably aware of at least a few shows airing on ABC Family -- 'The Secret Life of the American Teenager,' 'Make It or Break It,' and '10 Things I Hate About You' spring to mind.

The network has a new show premiering June 8 that looks to grab some of that audience. 'Pretty Little Liars' sounds like a cross between 'The Sisterhood of the Traveling Pants,' 'Desperate Housewives,' and 'Gossip Girl.' But it also looks pretty good. Here are four reasons why this show will be a hit.

Things are heating up this season in Pawnee, Indiana. E! Online reports that the 'Parks and Recreation' team have Leslie Knope, played by Amy Poehler, accidentally getting involved in a sex scandal that derails her plans for a city Santa's Village. Producer Mike Schur says, "There are rumors swirling about another city councilman scandal -- who was disgraced by cave sex in the 'Practice Day' episode -- and Leslie ends up getting photographed with him at a bar late at night by a tabloid newspaper."

As if that isn't enough, Leslie and Dave the Cop don't stand the test of time. "We were so lucky to get Louis C.K.," says Poehler of her character's love interest, "but he's starting his own show."

Luckily, it has just been confirmed by Entertainment Weekly that 'Parks' fans will see that role filled by none other than Poehler's real-life love, Will Arnett. Of course, Poehler and Arnett have worked together many times, including on 'Arrested Development' and in films such as 'Blades of Glory' and 'Monsters vs. Aliens.' So it's only natural that Arnett would stop by 'Parks.'

Arnett's arrival on the show will coincide with that of Justin Theroux who will, incidentally, also vie for Leslie's heart.

With thoughts of Arnett and Poehler teaming up again, we brainstormed some other real-life couples whose pairings would translate well to the small screen.

The CW's TCA panels today were full of beautiful people. It seemed like all the shows were about young pretty things in scandalous situations. Even the highly-anticipated Vampire Diaries didn't look much different, except some of the over-sexed high schoolers were vampires. But one show shined through the pretty clutter in the CW's new slate. Too bad we won't see it until early 2010.

That show is Life Unexpected, which CW programming head Dawn Ostroff described as "Juno meets Gilmore Girls." After seeing the pilot, I can agree with that description. It's sweet, warm, even a little bit hokey. In fact, it feels like a show that would have been on the old WB network. What the heck is it doing on the CW?

Happy or not that The CW will air a new version of Melrose Place, you must admit that you'll at least watch the premiere out of curiosity, especially if you watched the first show.

Tidbits about the show released these past weeks will have viewers tune in to know how the show will revive Sydney, a very much dead character played by Laura Leighton on the original series.

If that mystery is not enough to get you to tune in on Tuesday, September 8 at 9 p.m., maybe the new spoilers and casting information below will.

Premise: The CW is moving back into another familiar neighborhood for their second '90s show reboot -- and apparently, the tony Melrose Place apartments are still affordable for the struggling actors/filmmakers/rising stars of L.A.
