Martine Kimberley Sherri Ponting (born 14 May 1976), known professionally as Martine McCutcheon, is an English singer, television personality and actress. McCutcheon's first television role was the part of Mandy in the TV show Bluebirds in 1989. She also had minor success as one third of the pop group Milan in the early 1990s, but it was her role as Tiffany Mitchell in the BBC's EastEnders that she is best remembered for, as well has her role in the 2003 romantic comedy Love Actually. For the former she has won the 1997 National Television Award, whilst for the latter she received the 2004 Empire Award and the 2004 MTV Movie Award. She was written out of EastEnders at the end of 1998 to embark on a pop career, this time as a solo artist.

McCutcheon's debut studio album You Me & Us (1999) peaked at number 2 in the UK, was certified platinum and spawned the UK number 1 single "Perfect Moment" and two other top 10 hits. Her second studio album, Wishing (2000), was less successful, peaking at number 25, however produced two top 10 singles and was certified gold. Her pop career stalled due to the poor reception of her third album, Musicality in 2002, which only reached number 55 in the UK and received silver certification. She has since appeared in various television programmes, in films such as Love Actually as Natalie, and on stage in My Fair Lady, where her portrayal of Eliza Doolittle won her a Laurence Olivier Award in 2002. She released her autobiography, Who Does She Think She Is? in 2000. In 2016, she joined the ITV daytime show Loose Women as a regular panellist. The following year, she returned to music with the album Lost and Found.
