Although she loves her younger sister dearly, Kim Kardashian was not in the most festive of moods at Kendall Jenner's Sweet 16 birthday bash last month.

Kardashian family matriarch Kris Jenner threw her model daughter a lavish party in Los Angeles just four days after Kim filed for divorce from husband Kris Humphries.

Although the 31-year-old reality star gamely tried to get into the festivities, she wore sadness on her face like a stamp.

Not a happy camper: Kim Kardashian attended sister Kendall's Sweet 16 party just four days after announcing her split from Kris Humphries

The brunette beauty was in very few of the photographs that sister Khloe posted on her personal blog.

She attempted to smile in the shots she was actually featured in, but the grin didn't reach her eyes.

Physically, the middle Kardashian sister looked flawless as usual.

Birthday girl: 16-year-old Kendall, at least, seemed to have a blast at the fete

Her hair was coiffed within an inch of its life, her makeup was painted on to perfection and she looked stylish in a simple but sexy white top.

Her basketball player ex's absence was noticeable at the bash, which was attended by Khloe's husband, Lamar Odom, and Kourtney's boyfriend, Scott Disick.

Her unhappiness was also blatant, given the revelry going on around her at the Andaz West Hollywood hotel.

Khloe, 27, and Kourtney, 32, seemed to have a blast as they danced and partied with their younger sibling.

Father Bruce Jenner, brother Rob and sister Kylie, 14, were also on hand to enjoy the celebration at a West Hollywood hotel.

Although Kim's drama occurred behind-the-scenes, Kendall's drama was present for all and sundry to see in an episode of Keeping Up With the Kardashians which aired this week.

Unlike Kim, who's wedding reportedly cost $10 million, Kendall did not want to have a massive birthday bash.

She refused to let her mother plan a superfluous party in the Bahamas and opted to stay at home in Los Angeles instead.

She even refused to accept gifts, insisting people donate toys to charity instead.

On the E! show she said: 'Mom - I’m not going to do it! Do you not understand? You’re trying to make this bigger and bigger and it’s embarrassing me.'

'You’re just giving me this, you’re just handing me this and I don’t want it.'

Instead of the planned sponsored trip to the Bahamas for 75 of her closest friends, she insisted on a far more down-to-earth affair.

One person who may have regretted this decision was Kim, who, after her split from her husband of just 72 days, was clearly in need of a vacation.
