Kylie and Kendall Jenner: Dad Bruce was "Mad" about Khloé's Wedding

Khloé Kardashian and Lamar Odom tied the knot in an idyllic wedding ceremony on Sept. 27 with the full blessing of their friends and family, but when the youngest Kardashian sister first announced her surprise wedding to the basketball star, just two weeks after they started dating, one member of her family was concerned: Step-dad Bruce Jenner.

But was it a case of pot calling kettle black? The former decathlete, 49, married the sisters' mom Kris Jenner in 1992 after dating for just four months. "I was shocked because my dad was a little mad about it at first," Khloé's half-sister Kendall Jenner, 13, told OK! at Selena Gomez's "Kiss and Tell" album launch in Hollywood on Sept. 29. "I was shocked because it wasn't like he did it any different!"

Do the girls think their big sister rushed to the altar too soon? "Love is love," says Kendall (pictured, left), who signed on as a teen model with Wilhelmina Modeling Agency in June, "I don't think that they rushed it at all.  They just really love each other."

Despite being last minute, the ceremony "was beautiful," says Kendall, "and we could not believe it! I am just so happy for Khloé and Lamar."

And what exactly do the youngest members of the Kardashian-Jenner clan think of their new brother-in-law? "He is just the sweetest guy.  He is the nicest guy. He is funny and he is just so amazing!" Kendall raves to OK!. "And he is so tall!"

With Kourtney Kardashian, 30, expecting her first child with boyfriend Scott Disick in December, will 25-year-old Khloé start thinking babies? "It is a possibility now that they are married," says Kylie Jenner, 12.

And Kim Kardashian, 28, isn't too far behind.  According to the girls, their older sister and pro-football star Reggie Bush, 24, "are just on and off all of the time," but Kendall adds that Reggie is always "a part of the family."

It really is tough to keep up with the Kardashians!
