X17 XCLUSIVE - FIRST PIX OF KHLOE'S WEDDING!

X17online is the first to publish pix of Khloe Kardashian's wedding dress from this afternoon's nuptials!

Khloe and Los Angeles Lakers star Lamar Odom exchanged vows at music manager Irving Azoff's mansion in Beverly Hills in front of 250 guests, including mother Kris, stepfather Bruce Jenner, Kim, Kourtney and Robert Kardashian. Lamar's Lakers teammates, including Kobe Bryant and wife Vanessa were also there, as was singer Babyface, who serenaded the couple.

Our photographer tells us:

Khloe was a vision in white and Lamar looked so happy. It's hard to believe these two found love so quickly - after dating for just more than a month - but it seems like the real thing."

With Keeping Up With the Kardashians producer Ryan Seacrest in attendance, and rumors that the couple's wedding day was being financed by E!, some have speculated that the whole thing was an act for the cameras...

"It was a bit odd, though, that there were so many cameras around -- the place was beautiful but it did look a little like a Hollywood set. I can't imagine Khloe would get married for the wrong reasons though ... she seems like a nice girl."

So was is this marriage for real or what??!!
