Following their Florence wedding, newlyweds Kim Kardashian and Kanye West have begun a honeymoon in Ireland.

Dublin's The Irish Times quoted a witness at Cork Airport who said reality-TV star Kardashian, 33, and rapper West, 36, had arrived in a private jet shortly after 4 p.m. local time on Sunday. The plane carried two passengers and no entourage, the paper reported, adding that immigration and customs issues were dealt with onboard and that the couple then departed in a Mercedes with darkened windows.

When West performed concerts in 2006 and 2009 in Cork, the local paper the Evening Echo said, he had stayed at the Castlemartyr Resort, telling the staff of the 17th-century manor house's five-star hotel that he appreciated their respect for his privacy. Multiple sources suggest he and Kardashian are staying there now, although representatives for the resort told the Echo they would "make no comment at all" and told public broadcaster RTÉ TEN/The Entertainment Network they could "neither confirm or deny" the couple was staying there.

The Irish Times said other rumors placed them at County Limerick's Castle Oliver, which also declined to comment.

People magazine yesterday said the couple's 11-month-old daughter, North, is not accompanying them but flew out from Venice in the care of Kardashian's mother, Kris Jenner.

Meanwhile, the bride's younger brother, Rob Kardashian, 27 -- who was photographed arriving at Los Angeles International Airport Saturday night after having missed the wedding -- tweeted "good morning from Los Angeles" Monday shortly before deleting all his tweets, Us Weekly said. He started anew with various Memorial Day wishes and ended with a happy birthday to Scott Disick, his eldest sister Kourtney's longtime partner.

As well, Khloe Kardashian congratulated the Eastport-born Disick, who turned 31 Monday. She said on her Instagram account "Happy birthday to my partner in crime." Kardashian, 29, posted Disick's mug shot from an arrest in his youth alongside her mug shot from July 2008, when she turned herself in to serve a sentence stemming from a 2007 DUI arrest.

At 18, Disick was arrested by police in Riverhead after crashing his car there and failing a field sobriety test, according to the police report released by Splash News. Held overnight, he later pleaded guilty to driving while impaired by alcohol.
