Who wouldn't get stressed out?

After Mariah Yeater reportedly dropped her dubious paternity lawsuit against him last week, it looks like Justin Bieber's baby mama drama behind him -- which means his girlfriend Selena Gomez can breathe a sigh of relief.

The singer-actress, 19, opened up about the fracas (which made headlines worldwide) during a Thursday appearance on The Ellen DeGeneres Show.

"What a crazy two weeks it's been!" Ellen DeGeneres remarked to the star, 19.

"To say the least," the "Who Says?" singer admitted. "I have been [alright]."

With Yeater's lawsuit dismissed -- and unearthed text messages from Yeater about the real father of her baby further disproving her claims -- Gomez confided things are "good" and less stressful.

Indeed, Gomez and Bieber, 17, have shown a united, affectionate front throughout the scandal, in which Yeater claimed he fathered her 4-month-old son, Tristyn, during a quick encounter backstage at an L.A. concert a year ago.

Still, Gomez has been "exhausted and withdrawn," one source told Us Weekly. "She's supportive of Justin, but it's been very tough."
