'Baby Daddy' Season 4, Episode 21 Spoilers: Promo Released For Next Episode

The new promo for the next episode of "Baby Daddy," "What Happens in Vegas," has been released on the show's Facebook page.

Fans will see Bonnie Wheeler (Melissa Peterman) go crazy while trying to plan her wedding and bachelorette party after being engaged to Brad (Peter Porte).

In one scene, Tucker (Tahj Mowry) throws a wedding gown out of the window while Bonnie tries to get him to put it on.

Later, Danny Wheeler (Derek Theler) tries on the wedding dress insisting that he's making a sacrifice for his mom. Then his brother Ben (Jean-Luc Bilodeau) snaps a photo of Danny to put on the Internet while the rest of the gang laughs at him.

We also catch a glimpse of the gang walking into a hotel with the baby.

The gang is supposed to plan a bachelor party for Brad and a bachelorette party for Bonnie in the next episode.

"Riley (Chelsea Kane) is not thrilled when Bonnie promotes her to Maid of Honor and demands a crazy bachelorette party, while Brad asks Danny (Derek Theler) to be his best man and throw an epic, yet dignified, bachelor party," the show's description reads on SpoilersGuide.

The friends will also find out about Tucker's little secret in "What Happens in Vegas." He goes to visit Vegas each year to fulfill his dream of becoming a lounge singer. Yet, he tells the gang that he's going to a TV convention in Detroit.

"When the boys discover where Tucker really is, they decide to move Brad's bachelor party to the desert, which, of course, means Bonnie and Riley are right on their heels," the description continues. "When they accidentally discover Tucker's act, everyone agrees to enjoy their own nights, but things get very interesting when Bonnie ends up handcuffed to illusionist Peter Oliver (Dan Castellaneta). Meanwhile, Danny finally admits to Ben that he's in love with Riley."

The "What Happens in Vegas" episode of "Baby Daddy" airs on July 29 at 8:30 p.m.
