Stumped about what to get the girl who has everything? How about a sweet reminder of an awkward, bygone era?

That's exactly what Kim Kardashian did for longtime pal Nicole Richie's 31st birthday on Friday. The reality star posted an adorable, duck-face filled photo from Richie's 1995 birthday celebration on her official site.

"Happy birthday to my friend Nicole Richie," Kardashian, 31, wrote. "Many of you may not know that we've known each other for many years. I found this pic of us at Nicole's 14th birthday party! Awww, the memories."

Added the brunette beauty, "Happy birthday Nikki! Xo."

The birthday girl has yet to reply to her buddy's tribute, although she did take to Twitter Friday afternoon to thank her well-wishers for the bday love.

"THANK YOU for all the birthday wishes!!" Richie tweeted. "I feel so much wiser. Oh 30-year-olds, they're so silly . . . "
