and her already famous baby-to-be
were the guests of honor at their shower Sunday in Beverly Hills.
The Kardashian clan was joined by guests, including Kelly Osbourne
, Maria Menounos, Kimberly Stewart, NeNe Leakes and Mel B., to celebrate the new addition, due in July
The group enjoyed brunch – noshing on pancakes, waffles and fruit – before playing games and guessing baby names. Guests left with wreaths made of baby's breath in their hair.
As for the reality star's beau Kanye West
, he did attend after all
, arriving with Scott Disick and Lamar Odom.
"Kanye's whole family – all the women from his mom's side and dad's side – attended the shower," a source tells PEOPLE. "Kanye was so excited to have his family be there to join in the celebration with Kim's friends and family."
The mom-to-be, who has been defended by fellow celebs
for her sometimes-unconventional maternity style, wore a white long-sleeve pleated dress to the event.
"Kim and Kanye were so cute – he rubbed her belly," Kardashian's aunt Karen Houghton tells PEOPLE. "They're just really blessed. It's such a happy day."
The bash comes a month after Kardashian, 32, enjoyed a family vacation
in Greece sans West, and shortly after she finally divorced
husband Kris Humphries.
With all that behind her, the reality star can focus on the final task ahead – the delivery – not that she's sweating it.
"At the beginning, that was what I feared the most, and now, I mean, it's inevitable," she told HuffPo. "It's gonna happen – I'm really not worried or nervous."
Kardashian will announce the sex of the baby during the season premiere of Keeping Up with the Kardashians
, airing Sunday at 9 p.m. on E!
